The IRA-eligible platinum product list sits between gold and palladium in depth. Platinum is a hybrid precious metal: part monetary, mostly industrial. Retail bullion output is a thin layer on top of a much larger industrial supply chain that feeds auto catalysts, chemical processing, glass manufacturing, and the emerging hydrogen economy.

This page maps the entire eligible universe. It covers the .9995 fineness floor set by IRC 408(m)(3). It walks the sovereign platinum coins currently accepted by U.S. self-directed IRA depositories. It lists the LBMA Good Delivery bar refiners routinely booked into retirement accounts. It flags coins in legacy or intermittent production, and it names what does not qualify: proof-only issues at collector premiums and any platinum item that fails the fineness test.

Statutory basis: IRC 408(m)(3) and the .9995 fineness floor

The Internal Revenue Code bars IRAs from holding collectibles under IRC section 408(m)(1). Paragraph (3) carves a narrow exception for specific bullion coins and bars. Platinum runs through two limbs of the exception.

Subparagraph (A)(iii) names one platinum coin directly. It admits “a platinum coin described in section 5112(k) of title 31, United States Code.” That statutory cross-reference is what makes the American Platinum Eagle IRA-eligible by name, without any fineness or contract-market test.

Subparagraph (B) is the workhorse for every non-U.S. platinum product. It admits any gold, silver, platinum, or palladium bullion at a fineness equal to or exceeding the physical-delivery minimum on a regulated futures contract. The reference exchange for platinum is the CME NYMEX platinum futures contract. Its physical-delivery grade is .9995 fine.

Two operational notes flow from this structure. First, a platinum product does not need to be named in the coin statute to qualify. Fineness alone controls under (B). Second, most eligible platinum products sit exactly at .9995, not above.

If CME ever raised the platinum contract-market minimum, current products would lose eligibility on new orders from that date forward. The .9995 spec has been stable in practice, but it is conditional in principle. For the deeper walk-through, see the .995 and .9995 fineness requirement explained.

The IRS Publication 590-A approved-metals framework reflects the same rule. The IRS does not republish a product-by-product platinum list. Custodians and depositories cross-check the CME delivery grade and the LBMA Good Delivery platinum refiner list at intake.

Sovereign platinum bullion coins accepted for U.S. IRAs

Four sovereign platinum coins account for nearly all coin-form platinum booked into U.S. self-directed IRAs. Each meets the .9995 floor. Each is either directly named in the statute or qualifies through the (B) fineness pathway. Depository acceptance is routine on the standard bullion tier of each program.

Coin	Issuing mint	Fineness	Weight / face value	Statutory pathway
American Platinum Eagle	United States Mint	.9995	1 troy oz / $100 USD	IRC 408(m)(3)(A)(iii) via 31 U.S.C. 5112(k)
Canadian Platinum Maple Leaf	Royal Canadian Mint	.9995	1 troy oz / $50 CAD	IRC 408(m)(3)(B) fineness rule
Austrian Vienna Philharmonic Platinum	Austrian Mint	.9995	1 troy oz / 100 EUR	IRC 408(m)(3)(B) fineness rule
Australian Platinum Koala	Perth Mint	.9995	1 troy oz format most common in IRAs	IRC 408(m)(3)(B) fineness rule

The American Platinum Eagle is named in the statute. The U.S. Mint has struck the bullion tier since 1997 under 31 U.S.C. 5112(k). The coin is one troy ounce of .9995 fine platinum, $100 face value, single-size only for the bullion product. Proof and reverse-proof tiers exist for collector programs but carry premiums that rarely transfer at resale. For coin-level detail, see American Platinum Eagle IRA eligibility.

The Canadian Platinum Maple Leaf is struck by the Royal Canadian Mint at .9995 fineness. The coin is one troy ounce, $50 CAD face value, 34.0 mm diameter. The RCM launched the Platinum Maple Leaf bullion program in 1988. Production has been intermittent over the decades, with the modern .9995 spec consistent across each active mint year. It qualifies for U.S. IRA holding under the (B) contract-market fineness rule.

The Austrian Vienna Philharmonic Platinum is struck by the Austrian Mint at .9995 fineness. It is one troy ounce, 100 EUR face value. The platinum series was added to the long-running Vienna Philharmonic family (which also includes gold and silver Philharmonics) in 2016. It qualifies under (B). See Austrian Platinum Vienna Philharmonic IRA eligibility for the coin-level page.

The Australian Platinum Koala is struck by the Perth Mint at .9995 fineness. The series has been minted in various runs since 1988, with the one-troy-ounce format most relevant to IRA holdings. Coin availability in the U.S. wholesale channel can be thinner than for the American, Canadian, and Austrian programs. It qualifies under (B) when the specific-year issue is confirmed at .9995 fine.

Historical and intermittent sovereign platinum coins

Several other government mints have issued platinum coins on an irregular or discontinued basis. Depository acceptance depends on the specific year, the fineness of the issue, and whether the custodian has cleared the item on its internal acceptance list.

The Isle of Man Noble, first struck by the Pobjoy Mint in 1983 at .9995 fineness, is the historical outlier. Older tubes still circulate in the wholesale market. Custodian acceptance is inconsistent, and the coin is thinly traded compared with the modern sovereign programs. It qualifies under (B) when acceptance is confirmed in writing at account opening.

The British Britannia Platinum, the Chinese Platinum Panda, and various platinum commemoratives from other national mints appear intermittently in dealer catalogs. Individual issues may or may not meet the .9995 floor, and IRA depositories generally do not book them at standard intake unless the year and fineness are verified against the mint’s published specifications. Retirement buyers focused on platinum content are better served by the four currently-produced sovereign programs above or by LBMA Good Delivery bars.

The operational rule for a retirement holding is straightforward. Stick to the four currently-produced sovereign coins or to LBMA Good Delivery bars. Legacy platinum coins fit a numismatic collection, not a retirement holding sized for platinum content.

Platinum bars from LBMA Good Delivery accredited refiners

Bars are the second eligible platinum product family. The statutory test at IRC 408(m)(3)(B) applies to bars as it does to coins: .9995 fine or higher, from a refiner accredited on a recognized commodity exchange or by a national government mint. The industry-standard credential is the London Bullion Market Association Good Delivery list for platinum.

The LBMA Good Delivery framework and the CME NYMEX platinum contract’s approved-brand list serve the same operational role for platinum that they do for gold. A bar refined by a listed producer at .9995 or higher clears the statutory test. A bar from a non-listed refiner does not, even at .9999 fine. For the full framework walk-through, see LBMA Good Delivery bars explained.

Refiners routinely booked by U.S. self-directed IRA depositories for platinum bars include Swiss and continental European names. PAMP Suisse, Valcambi, Argor-Heraeus, Heraeus, and Metalor each hold LBMA Good Delivery accreditation for platinum. Each strikes retail platinum bars at .9995 or higher. Older Johnson Matthey platinum bars remain IRA-eligible when the hallmark and assay card are intact.

Common retail platinum bar sizes are 1 troy ounce and 10 troy ounces. Smaller gram-weight bars (1 g, 5 g, 10 g) are less common in the platinum catalog than in the gold catalog. Bars ship in tamper-evident assay cards for the smaller weights and rigid cases with paper assay certificates for the larger ones.

Depositories accept the bar in original sealed refiner packaging with the serial number on the card matching the stamped bar. Re-poured, re-serialized, or removed-from-assay-envelope bars are rejected at intake. That is a depository risk-control rule, not an IRS rule, and it is enforced uniformly across the standard custodian-recognized depository network.

What is not IRA-eligible: proof premiums and collectible platinum

Two categories of platinum sit outside a properly-structured retirement holding, even where the raw fineness clears the .9995 floor.

The first is proof or special-finish platinum coins bought at collector premiums. A proof American Platinum Eagle at .9995 fine is legally IRA-eligible under 408(m)(3)(A)(iii). The statute does not distinguish finish. The economic problem is different.

Proof platinum coins can carry dealer premiums of 50 to 90 percent over spot, or higher on limited-mintage issues. That collector premium does not reliably transfer at resale. A retirement account paying a proof premium on entry generally sees only the bullion value on exit. For the eligibility-versus-economics analysis, see proof coins versus bullion IRA eligibility.

The second is collectible platinum that fails the fineness test or the refiner test. Historical platinum coins struck below .9995 fine do not clear the (B) rule. Platinum bars from non-LBMA, non-COMEX-approved refiners are outside the statutory pathway. Numismatic platinum items with a hallmark that a depository cannot verify against a recognized list are rejected at intake.

All three cases fall under the collectibles prohibition of IRC 408(m)(1). Personal receipt of such items by an IRA owner would trigger a deemed distribution. For the underlying prohibition, see the IRC 408(m) collectibles rule explained.

The clean rule for a retirement account is a two-part filter. First, .9995 fine or higher. Second, either named in the statute (American Platinum Eagle) or from a refiner or sovereign mint whose product is booked by the depository against a recognized fineness and origin credential. Everything else stays out of the IRA and into a taxable holding if the buyer still wants exposure.

Why the eligible platinum universe is narrower than gold

The eligible platinum product list is intrinsically shorter than the gold list. Platinum is a smaller market than gold by traded volume. Industrial demand dominates the annual balance. Sovereign mints outside the primary producing regions have historically favored gold and silver programs where domestic bullion demand supports a full retail catalog.

Primary mine supply is concentrated. South Africa accounts for the majority of world platinum mine production. Russia, Zimbabwe, Canada, and the United States account for most of the balance. Refining capacity for LBMA Good Delivery platinum bars sits in a handful of European operations plus the sovereign refiners in the producing countries.

The result is a four-coin sovereign roster plus a handful of accredited bar refiners. That is the entire IRA-eligible universe for coin-form and bar-form platinum. Retail investors comparing the platinum catalog against the much deeper gold catalog often expect a longer list than the market offers.

Practical buying notes: premiums, availability, dealer selection

Dealer premiums on IRA-funding platinum orders differ meaningfully by product tier. The FINRA Investor Alert on Investing in Precious Metals flags platinum premium volatility explicitly. General ranges as of August 14, 2026:

Platinum bars. One-ounce and ten-ounce bars from PAMP, Valcambi, Argor-Heraeus, and Heraeus typically carry premiums of roughly 5 to 10 percent over the LBMA platinum fix on a retirement-account order.
Canadian Platinum Maple Leaf. Industry-reported dealer premiums on the standard bullion coin run around 10 to 18 percent over spot.
Austrian Vienna Philharmonic Platinum. Premiums typically sit in a similar 10 to 18 percent band, with occasional volatility on years of thin dealer inventory.
American Platinum Eagle. Premiums usually run 12 to 20 percent over spot on a bullion order, reflecting the U.S. Mint’s relatively modest annual mintage.
Proof or special-finish issues. Proof platinum coins can carry premiums of 50 to 90 percent over spot. The proof premium does not reliably transfer at resale.

Dealer availability is narrower than for gold product lines. Not every gold IRA dealer stocks a full platinum book. Some list platinum on request and source through the wholesale channel per order. Delivery time on a platinum order can run days longer than a comparable gold order for that reason. Depository availability is also narrower: fewer IRS-approved depositories hold material platinum inventory than gold or silver.

Buy-back spreads reflect the same market depth. A dealer’s buy-back on standard platinum bullion typically sits at 3 to 7 percent under spot in normal conditions. That is tighter than palladium and wider than gold. Sizing an allocation with the round-trip spread in mind matters more on platinum than on the deeper metals.
