Quick answer: A California heir who inherits gold coins gets a fair-market-value basis reset on the date of the decedent's death under 26 U.S.C. Section 1014, so selling promptly at that value usually produces zero taxable gain. Do not clean the coins, get a written date-of-death appraisal, confirm probate posture, then sort into bullion, numismatic, and cull buckets and match each to a matching channel.

Short on time? The essentials

Cleaning inherited coins destroys the collector premium; a whizzed or dipped 1904 Liberty Head Double Eagle can lose most of its numismatic value even though the gold weight is unchanged.
Federal Section 1014 gives the heir a stepped-up basis equal to the fair market value on the date of the decedent's death, so a sale at that value produces zero capital-gain tax.
California conforms to the federal step-up rule and taxes the same capital gain as ordinary income at rates up to 12.3 percent, plus a 1 percent Mental Health Services Tax on taxable income above $1,000,000 (Franchise Tax Board 2024 tax rate schedule).
Federal collectibles long-term capital gain is capped at 28 percent under 26 U.S.C. Section 1(h)(4) and Section 408(m), applied only to the gain above the stepped-up basis, never to the basis itself.
California Probate Code Section 13100 lets a successor collect tangible personal property, including coin collections, by written affidavit after 40 days when the gross estate value in California stays at or below $166,250, adjusted per Section 890.
Intestate succession runs through Probate Code Sections 6401 and 6402; a surviving spouse takes all community property and a fraction of the separate property depending on which relatives survive the decedent.
The three-bucket sort matters because bullion coins clear at a dealer near spot, numismatic coins need a specialist or auction, and cull or damaged coins go to a refiner or scrap counter.

Do not clean the coins before anyone sees them

The single most expensive mistake a California heir can make with an inherited coin collection is cleaning the coins. Every abrasive cleaning, dip, polish, or scrub destroys the original mint surfaces that grading services and collectors pay for. The gold weight does not change; the collector premium can vanish.

Professional Coin Grading Service (PCGS) and Numismatic Guaranty Company (NGC) are the two main US grading services. Both label coins that have been cleaned as "Details" grades, which sell at a fraction of comparable problem-free examples. A whizzed or harshly cleaned 1904 Liberty Head Double Eagle can trade at half or less of what an original-surface example brings.

Handle any coin only by the edge, over a soft towel, in cotton or nitrile gloves. Do not remove coins from 2x2 cardboard flips, plastic tubes, or slab holders. If a coin is in a PCGS or NGC slab, leave it there; the holder is the grade and the guarantee. If a coin is loose in a Whitman folder, leave it in the folder for the appraiser.

The same rule applies to old paper envelopes, dealer tickets, and hand-written inventory notes the decedent left with the coins. Those slips carry provenance evidence. A collector who tracked purchase dates or coin-show sources with each coin leaves a trail that supports value and, where relevant, basis history.

Get a written date-of-death inventory and appraisal

The heir's first business step is a written inventory and appraisal as of the date of the decedent's death. That date matters because federal law under 26 U.S.C. Section 1014 sets the heir's tax basis in inherited property at the fair market value on that date, not at what the decedent originally paid. A written appraisal locks in that number for the IRS and the Franchise Tax Board.

An inventory identifies each coin by type, date, mint mark, grade, and any grading service certification number. An appraisal states a fair market value for each coin as of the reference date, with a summary of the methodology and comparable sales. The two documents together are what a probate court, an insurer, and a future buyer expect to see.

Appraiser credentials matter. Look for an American Numismatic Association (ANA) member, a Professional Numismatists Guild (PNG) dealer, or a member of the American Society of Appraisers with a numismatic specialty. IRS Publication 561 sets the qualified-appraisal standard for tangible personal property; the same standard is the safest one to meet for the estate, even though the immediate purpose is basis, not donation.

IRS Publication 559 (2025), Survivors, Executors, and Administrators, is the tax-side reference for the personal representative of the estate. It covers the federal filing obligations that accompany a decedent's final return and the estate's own income tax return where one is required, and it explains how the basis step-up flows to beneficiaries.

Community property, separate property, and intestate rules

California is a community-property state. Coins acquired during the marriage with community funds are community property, and each spouse owns an undivided one-half interest under Family Code Section 760. Coins the decedent brought into the marriage, received by gift, or inherited are separate property under Family Code Section 770.

The distinction changes the basis math. When a coin was community property, the surviving California spouse gets a full basis step-up on both halves under 26 U.S.C. Section 1014(b)(6), sometimes called the double step-up. When a coin was the decedent's separate property, only the decedent's interest steps up. Documentation of when and how each coin entered the collection matters for that reason.

If the decedent left a will, the will controls distribution. If the decedent died without a will, California Probate Code Sections 6401 and 6402 govern intestate succession. Section 6401 gives a surviving spouse the entire one-half of the community property that belonged to the decedent, and a share of separate property that depends on which other relatives survive.

Section 6402 walks the separate property down through issue (children and their descendants), then parents, then siblings, then more distant kin, if no spouse survives. A California heir who is not the surviving spouse takes coins that were part of the separate-property estate through this order, not automatically as a "next of kin" default.

Small-estate affidavit under Probate Code Section 13100

Full probate is not always required. California Probate Code Section 13100 lets the successor of the decedent collect tangible personal property, including a coin collection, by a written affidavit once 40 days have passed after the death. The affidavit path applies when the gross value of the decedent's real and personal property in California stays at or below $166,250, adjusted periodically under Section 890 per AB 2016 effective January 1, 2025.

The affidavit procedure does not require a court appearance or an attorney. The successor presents a signed affidavit to the person or institution holding the property, along with a certified death certificate and any supporting title documents. That person can be a bank safe-deposit-box custodian, a coin dealer holding pieces for review, or a sibling holding coins for the estate.

Larger estates go through full probate. Coin collections in a full probate estate are appraised by a court-appointed probate referee under Probate Code Sections 8900 through 8909, at a statutory fee of 0.1 percent of the appraised value, subject to a minimum and maximum. The California Courts self-help pages summarize the current small-estate threshold and the probate procedures for consumers without an attorney.

The safe-deposit box holding the coins can itself trigger a specific procedure. Under Probate Code Sections 331 and following, a successor can access a decedent's box to search for a will and remove tangible personal property, subject to bank policy and identification requirements. Photograph the contents on opening.

Sort the collection into three buckets

Once the appraisal is done, sort the inventory into three buckets. Each bucket routes to a different selling channel, and the sort protects the heir from underselling numismatic pieces to a bullion dealer or overpaying auction fees on a common gold coin.

Bucket one is bullion coins. These are modern government coins bought and sold on gold content, at a modest premium over spot. American Gold Eagles (1 oz, 1/2 oz, 1/4 oz, 1/10 oz), Gold Buffaloes (1 oz .9999), Canadian Maple Leafs, South African Krugerrands, Austrian Philharmonics, and Australian Kangaroos are the common examples. Wholesale premium over spot for a common-date one-ounce Gold Eagle typically runs a few percent.

Bucket two is numismatic coins with a real collectible premium above melt. Pre-1933 US gold (Liberty Head Double Eagles, Saint-Gaudens Double Eagles, Indian Head Eagles), key-date Morgan silver dollars, early US commemoratives, and world gold coins with collector demand belong here. Slabbed pieces from PCGS or NGC carry the grade and eye appeal that drive auction hammer prices.

Bucket three is cull and generic scrap. Heavily worn common-date circulated silver, damaged or holed coins, jewelry-mount removals, and low-grade generic gold with no collector value belong here. The cull bucket sells at gold or silver content minus a refiner spread. Do not mix cull with numismatic pieces in the same shipment; a scrap buyer will not sort them for you.

Match each bucket to the right selling channel

Bullion coins clear at a local coin shop, a national bullion dealer (APMEX, JM Bullion, Kitco, SD Bullion), or a wholesale bullion desk. Buy-side spreads for common-date modern bullion coins typically run 1 to 3 percent below wholesale ask, higher for fractional coins. Get two or three offers on the same day; bullion prices move minute to minute.

Numismatic coins go to a numismatic specialist. Two channel choices dominate. A well-known auction house (Heritage Auctions, Stack's Bowers Galleries, Legend Rare Coin Auctions, Great Collections) reaches the collector base that pays retail prices. Seller commissions typically run 10 to 15 percent, sometimes zero with a buyer's premium of 17.5 to 20 percent. Timelines run two to four months from consignment to settlement.

A specialist numismatic dealer buys outright for a faster, private transaction. Outright offers typically sit 15 to 30 percent below auction retail for common numismatic pieces, tighter for high-demand key dates. The Professional Numismatists Guild (PNG) publishes a code of ethics and a dealer directory that a California heir can use to identify credentialed buyers.

Cull and scrap coins go to a refiner or a scrap buyer. Refiners (A-Mark, Manfra Tordella & Brookes, Garfield Refining) pay content value minus a spread of 3 to 15 percent for standard karat lots. A retail cash-for-gold counter pays a wider spread, sometimes 20 to 40 percent below content, in exchange for a walk-in cash transaction. Cross-check the metal content and the paying rate before shipping any lot.

Federal and California tax treatment on the sale

The federal side of the tax equation has two moving parts: the stepped-up basis and the collectibles rate. Section 1014 sets the basis at fair market value on the date of death. Section 1(h)(4) and (5) treat gain on the sale of a collectible held more than one year as a 28 percent maximum long-term capital gain, and Section 408(m) defines a collectible to include coins other than certain listed bullion coins.

The 28 percent cap applies to the gain above basis, never to the basis itself. A California heir who sells at the appraised date-of-death value produces zero gain and owes zero federal capital-gain tax on the sale. A sale at $60,000 on a $50,000 basis produces $10,000 of long-term capital gain, and the federal tax on that gain is capped at 28 percent, or $2,800, if the taxpayer's regular rate would otherwise be higher.

Taxpayers in lower brackets pay their ordinary rate, up to that 28 percent ceiling, on collectibles gain. The IRS 28 percent Rate Gain Worksheet in the Schedule D instructions is where the calculation actually happens on the return. The Net Investment Income Tax under Section 1411 adds a 3.8 percent surtax on collectible gain for taxpayers above the modified adjusted gross income thresholds.

California conforms to the federal step-up rule but does not give capital gains a preferential rate. Gain above basis is ordinary income for California, taxed at marginal rates from 1 percent to 12.3 percent under the Franchise Tax Board 2024 tax rate schedule. A separate 1 percent Mental Health Services Tax applies to taxable income above $1,000,000 under Revenue and Taxation Code Section 17043.

A California heir in the 9.3 percent state bracket who realizes $10,000 of collectibles gain pays $2,800 federal (28 percent) plus $930 California (9.3 percent), a combined $3,730 on that gain, before any Section 1411 surtax. The stepped-up basis portion of the proceeds is not taxed at all. That is why prompt sale at the appraised value is usually the tax-simplest exit for a California heir.

Bucket, channel, and tax comparison table

Three coin buckets, matching selling channels for a California heir, typical net proceeds range, and the federal plus California tax treatment on any gain above the stepped-up basis under 26 U.S.C. Section 1014.
Bucket	Typical contents	Matching channel	Typical net proceeds	Federal and California tax on gain above basis
Bullion coins	Gold Eagle, Gold Buffalo, Krugerrand, Maple Leaf, Philharmonic, Kangaroo	Local coin shop, national bullion dealer, wholesale desk	1 to 3 percent below wholesale ask on common-date one-ounce coins	Federal collectibles LTCG capped at 28 percent (Section 1(h) and Section 408(m)) plus California ordinary income up to 12.3 percent
Numismatic coins	Pre-1933 US gold, slabbed key dates, world gold rarities, early commemoratives	Auction house (Heritage, Stack's Bowers) or PNG-member specialist dealer	Auction: retail hammer minus 10 to 15 percent seller commission; dealer: 15 to 30 percent below auction retail	Federal collectibles LTCG capped at 28 percent plus California ordinary income up to 12.3 percent
Cull and scrap	Worn common-date silver, damaged coins, holed pieces, low-grade generic gold	Refiner (A-Mark, Garfield) or cash-for-gold counter	60 to 97 percent of gross metal content value, depending on channel and lot size	Federal collectibles LTCG capped at 28 percent plus California ordinary income up to 12.3 percent

Proceeds ranges reflect typical California market conditions in 2026 and are not dealer quotes. Federal tax rate from 26 U.S.C. Section 1(h)(4) and Section 408(m). California rate from Franchise Tax Board 2024 tax rate schedule, plus 1 percent Mental Health Services Tax on income above $1,000,000 (Revenue and Taxation Code Section 17043).

Worked example: a $50,000 collection sold from Sacramento

Worked example. A Sacramento heir inherits her father's coin collection on August 13, 2026. A written date-of-death appraisal by an ANA-member appraiser sets the fair market value at $50,000, itemized as $30,000 in modern bullion Gold Eagles and Buffaloes, $15,000 in slabbed pre-1933 US gold, and $5,000 in cull silver and damaged pieces.

Basis reset. Under 26 U.S.C. Section 1014, the heir's tax basis in the collection is $50,000, not what her father paid decades ago. A sale at $50,000 total produces zero gain and zero federal or California tax on the sale.

Channel routing. The heir ships the bullion to a national dealer that quotes 2 percent below wholesale, netting $29,400 on the $30,000 lot. She consigns the pre-1933 slabbed pieces to Heritage Auctions with a 10 percent seller commission and a zero buyer's premium tier; the pieces realize $15,000 gross for a net of $13,500. She ships the cull silver to a refiner paying 92 percent of content, netting $4,600 on the $5,000 lot.

Total net. Combined net proceeds of $47,500 against a stepped-up basis of $50,000 produce a $2,500 capital loss, deductible against other capital gains and, if none, up to $3,000 per year against ordinary income under 26 U.S.C. Section 1211. The California treatment tracks the federal calculation.

Wait five years. At a labeled illustrative 5 percent annual gold price path, the same three lots grow to about $63,814 gross. The gain is $13,814. Federal tax at 28 percent is $3,868. California tax at 9.3 percent is $1,284. Combined tax on the gain is $5,152. Net after-tax cash to the heir is $58,662. Prompt sale at basis nets $50,000 tax-free; a five-year wait nets $8,662 more before inflation and storage cost.

Net after-tax proceeds by holding period

The chart below stacks the two decisions for a California heir with a $50,000 stepped-up basis: sell immediately at basis, or hold for five, ten, or twenty years at two illustrative gold price paths. Immediate sale nets the full basis with zero tax. Longer holds add appreciation but the gain above basis is taxed at the combined 37.3 percent collectibles rate used in the worked example above.

Grouped bar chart comparing net after-tax cash to a California heir who inherits a gold-coin collection valued at $50,000 fair market value on the date of the decedent's death, the stepped-up basis under 26 U.S.C. Section 1014. Selling immediately at that value nets $50,000 with zero federal or California tax because there is no gain above basis. A five-year hold at a labeled illustrative 3 percent annual gold price path nets $54,994 after tax; at a 5 percent path, $58,661. A ten-year hold nets $60,782 at 3 percent and $69,716 at 5 percent. A twenty-year hold nets $75,272 at 3 percent and $101,831 at 5 percent. Tax on gain uses 28 percent federal collectibles long-term capital gain (26 U.S.C. Section 1(h) and Section 408(m)) plus 9.3 percent California marginal ordinary rate (Franchise Tax Board 2024 tax rate schedule), a combined 37.3 percent on the gain only, not on the stepped-up basis. — Net after-tax cash on a $50,000 inherited gold-coin collection at four sale dates and two illustrative gold price paths. Immediate sale nets basis with zero tax; longer holds add appreciation but the gain above basis is taxed at the combined 37.3 percent collectibles rate.

The chart is not a forecast. The 3 percent and 5 percent paths are illustrative arithmetic, not a projection of future gold prices. Real returns depend on the actual gold price at each future sale date and on the taxpayer's actual federal and California brackets in that year. Changes to the collectibles rate or to California conformity rules can also shift the after-tax result.

Documentation the buyer will ask for

A dealer, refiner, or auction house buying or accepting consignment from an estate will ask for specific documentation to confirm that the seller has authority to transfer title. The list matters because a buyer who cannot document chain of title exposes the coins to reclaim risk from another heir, a creditor, or a probate court later.

Government-issued photo identification for the seller. California driver license or ID card, plus a matching Social Security number if the transaction crosses the $10,000 IRS Form 8300 threshold.
Certified death certificate for the decedent. Ordered from the California Department of Public Health or the county recorder; one original per selling channel is usually enough.
Small-estate affidavit under Probate Code Section 13100 where the estate qualifies. The written affidavit, signed under penalty of perjury, is what the buyer relies on to release funds or accept consignment.
Letters testamentary or letters of administration for a full-probate estate. The court-issued letters name the personal representative and grant authority to transact on estate assets.
Written date-of-death appraisal. Not always required by the buyer, but expected by the IRS and Franchise Tax Board for basis documentation on the heir's return.
Written inventory with grading service certification numbers for slabbed pieces. PCGS and NGC each provide a public verification lookup that confirms the coin against its holder.

Refiners, national bullion dealers, and auction houses each have their own compliance intake and know-your-customer procedures. Ask each buyer for the intake form before shipping any coins. Confirm the shipping address, insured carrier, declared value, and settlement timeline in writing before packing anything.

Step-by-step: how the heir should work the estate

Secure the collection and stop all handling. Move the coins to a locked location with a signed chain of custody. Do not clean, sort, remove from holders, or photograph coins outside their flips or slabs. Keep the safe-deposit-box key inventory intact.
Order certified death certificates. Request several originals from the California Department of Public Health or the county vital records office. Each selling channel and each financial institution will keep one on file.
Get a written date-of-death inventory and appraisal. Engage an ANA-member, PNG-affiliated, or ASA-credentialed numismatic appraiser to inventory and value the collection as of the decedent's date of death. Budget $150 to $500 per hour for on-site work.
Confirm probate posture with a California attorney or self-help center. If the estate qualifies for the small-estate affidavit under Probate Code Section 13100, prepare the affidavit. Larger estates open a probate case and receive a court-appointed referee.
Sort into bullion, numismatic, and cull buckets. Use the appraisal as the sorting basis. Bullion goes to a coin shop or bullion desk. Numismatic goes to an auction house or a PNG-member specialist. Cull goes to a refiner.
Get two or three offers per bucket on the same day. Bullion prices move minute to minute; numismatic prices vary by buyer specialty. Match offers to the same lots for a like-for-like comparison. Do not accept a same-day take-it-or-leave-it pressure offer.
Ship insured, tracked, and recorded. USPS Registered Mail with full declared value, or a private carrier with numismatic insurance, is the standard for interstate coin shipments. Photograph the packing and keep tracking numbers.
Report the sale on your federal and California returns. A sale at the appraised date-of-death value produces zero gain and no tax. A sale above the appraised value produces long-term capital gain reported on Schedule D and Form 8949 federally, and on Schedule CA on the California Form 540.

When selling now is a bad idea

Prompt sale at the appraised value is usually the tax-simplest path, but it is not the right path in every case. Several situations argue for holding, not liquidating, the inherited collection.

A sentimental piece with meaning inside the family. A grandfather's set of Mercury dimes or a graduation-gift Saint-Gaudens is worth keeping when a child, sibling, or grandchild will value it more than the after-tax cash.
A signed, pedigreed, or condition-rarity piece that a specialist has not yet reviewed. A slabbed MS-67 Saint-Gaudens or a pedigreed coin from a famous collection can move by multiples when the right specialist gets a look. Do not sell to the first offer.
An estate in dispute or with unclear title. Coins named in a specific bequest, subject to a beneficiary designation, or contested by another heir stay with the estate until the probate court resolves title. Do not sell a contested coin.
Timing that would push the heir into a higher bracket. A large realized gain in a year with an unusual bonus, a business sale, or a Roth conversion may spill into a higher federal or California marginal rate. Spreading the sale across two tax years can lower the total tax bill.
Coins subject to a pending IRS or state examination on the decedent's return. Do not liquidate assets that a tax authority may need to trace or value while an exam is open. Wait for the estate's tax matters to close first.

Common questions California heirs ask

Do I owe federal tax if I sell inherited coins at the appraised date-of-death value?

No. Under 26 U.S.C. Section 1014 the heir's basis in inherited coins is the fair market value on the date of the decedent's death. A sale at that value produces zero long-term capital gain and no federal capital-gain tax. A sale above that value produces gain taxed at the collectibles rate up to 28 percent under Section 1(h)(4) and Section 408(m).

Does California give inherited coins a step-up in basis too?

Yes. California generally conforms to the federal step-up rule under Revenue and Taxation Code Section 18031, which incorporates federal basis rules by reference. The California-taxable gain uses the same stepped-up basis. California taxes the gain as ordinary income at rates up to 12.3 percent, plus a 1 percent Mental Health Services Tax on taxable income above $1,000,000 under Section 17043.

Should I clean the coins to make them look better before I sell?

No. Cleaning strips original mint surfaces that grading services and collectors pay for. PCGS and NGC label cleaned coins as "Details" grades that sell at a fraction of comparable original-surface examples. A whizzed 1904 Liberty Head Double Eagle can trade at half or less of the price a problem-free coin brings. Handle only by the edge, never scrub, dip, or polish.

Do I need full probate to sell a coin collection in California?

Not always. California Probate Code Section 13100 lets the successor of the decedent collect tangible personal property, including coins, by a written affidavit once 40 days have passed after death. The affidavit path applies when the gross value of the decedent's California property stays at or below $166,250, adjusted per Section 890 per AB 2016 effective January 1, 2025. Larger estates open a full probate case with a court-appointed probate referee.

How do I prove the date-of-death fair market value to the IRS?

With a written appraisal from a credentialed numismatic appraiser, dated as of the reference date, listing each coin by type, date, mint mark, grade, and value. IRS Publication 561 sets the qualified-appraisal standard. IRS Publication 559 covers the personal representative's federal filings. Keep the appraisal with the estate file and with the heir's tax records for the year the coins are sold.

Should I sell to the first dealer who offers a fair price?

No. Get two or three offers on the same lots, on the same day for bullion coins because spot prices move continuously. For numismatic pieces, compare a specialist dealer outright offer against an auction estimate from Heritage Auctions, Stack's Bowers Galleries, or Legend Rare Coin Auctions. The right channel depends on the specific coins in the bucket.

What if the inherited coin collection is in a bank safe-deposit box?

Access follows the bank's policy and California Probate Code Sections 331 and following. A successor may access the box to search for a will and remove tangible personal property, subject to the bank's identification and authorization requirements. Photograph the entire contents at opening. Do not remove coins from a jointly leased box without documenting the source of funds and joint ownership status.

What if I live outside California but the coins are in a California estate?

California law governs probate and small-estate procedure for property located in California, regardless of where the heir lives. Federal Section 1014 basis rules apply to the heir wherever they file. Once title transfers under California procedure, the coins can move to the heir's home state. State-level sales and use tax on any later resale then follow the heir's state, not California.
