The tax code does not let an IRA hold just any gold or silver. IRC Section 408(m) generally treats coins and bullion as collectibles, which IRAs cannot own, then carves out specific exceptions: certain coins minted by the United States and, for bullion, metal that meets minimum fineness and is held by a trustee. In practice that means gold at .995 fineness or higher, silver at .999, and platinum and palladium at .9995, plus a short list of coins that qualify by name.
The framework behind those rules, including the custody requirement and what happens if an IRA acquires a non-qualifying item, is covered in IRS Rules for Gold IRAs: Approved Metals and Purity Standards. This article is the applied version: a coin-by-coin look at what typically qualifies, what does not, and the gray areas worth confirming with your custodian before any purchase.
One note before the lists. Eligibility is about the tax rules, not about investment merit. All of these products track the same underlying metals, whose prices fluctuate and can lose value, and none of them pays income or dividends. Eligibility tells you what an IRA may hold, not what it should.
Gold Coins and Bars That Qualify
| Product | Purity | Notes | |---|---|---| | American Gold Eagle | 91.67% | Eligible by statutory exception despite falling below .995 | | American Gold Buffalo | .9999 | The US Mint's 24-karat bullion coin | | Canadian Gold Maple Leaf | .9999 | Meets the fineness test comfortably | | Austrian Gold Philharmonic | .9999 | European bullion coin, widely traded | | Australian Gold Kangaroo | .9999 | Perth Mint bullion coin | | Gold bars and rounds, .995+ | .995 minimum | Must come from a refiner accredited by an exchange such as NYMEX/COMEX or a national accreditation body |
The American Gold Eagle deserves a word. At 91.67% gold (the balance is silver and copper for durability), it misses the .995 threshold, yet Congress named it eligible directly in the statute. It is the one major coin that qualifies by exception rather than by fineness.
For bars and rounds, the accreditation requirement does real work. Products from refiners on recognized good-delivery lists, such as LBMA-listed names, qualify in practice. A generic bar from an unknown source may not, no matter what its stamp claims.
Silver Coins and Bars That Qualify
| Product | Purity | Notes | |---|---|---| | American Silver Eagle | .999 | US Mint bullion coin, named in the statute | | Canadian Silver Maple Leaf | .9999 | Exceeds the minimum | | Austrian Silver Philharmonic | .999 | Meets the threshold | | Silver bars and rounds, .999+ | .999 minimum | Same accredited-refiner requirement as gold |
One practical note on silver: because it is priced far below gold, holding the same dollar value means storing much more physical bulk, which can matter at percentage-based or per-item storage rates.
Popular Coins That Do NOT Qualify
| Product | Why it fails | |---|---| | South African Krugerrand | 91.67% purity with no statutory exception, unlike the Gold Eagle | | Pre-1933 US gold coins (Liberty, Saint-Gaudens, Indian Head) | Numismatic collectibles; purity around 90% and no exception | | British Sovereign | 91.67% purity, no exception | | Most historic and commemorative world coins | Below fineness thresholds, or valued as collectibles | | Graded, "slabbed," or certified rare coins | Generally treated as collectibles regardless of metal content |
The Krugerrand trips up many buyers because it is one of the most widely traded bullion coins in the world. It is a perfectly liquid coin outside an IRA; it simply was not given the exception the Gold Eagle received, and its 91.67% purity keeps it below the bullion threshold.
If an IRA does acquire a collectible, IRC Section 408(m) treats the amount invested in that item as distributed to you, taxable and potentially subject to the 10% early withdrawal penalty before age 59 1/2. The account survives, but the mistake is expensive. Worth knowing too: collectibles held outside an IRA face a long-term capital gains rate of up to 28%, which is part of why the eligibility line matters in both directions.
The Proof Coin Question
Proof coins, the mirror-finish collector versions of bullion coins struck by the same mints, occupy an awkward middle ground. A proof American Gold Eagle or Silver Eagle can be IRA-eligible if it otherwise meets the requirements and, in the IRS's framing for certain coins, remains in its original mint packaging with certificate.
Eligible, however, is not the same as cost-equivalent. Proofs typically carry substantially higher premiums over the metal's spot price than standard bullion versions, and the resale market may not return that premium when you sell. Before choosing proofs, ask for the all-in per-ounce cost next to the standard bullion version of the same coin. The mechanics of markups are explained in Dealer Markups and Spot Price: The Largest Gold IRA Cost.
Gray Areas: Confirm Before You Buy
A few situations call for a direct question to your custodian before money moves:
- Graded and slabbed coins. Once a coin is encapsulated and graded by a third-party service, it is generally being sold for collectible value, and custodians typically treat it as ineligible even if the underlying coin type would qualify.
- Coins you already own. Even a fully eligible coin cannot be contributed to your IRA from your personal collection. Contributions are made in cash, and the IRA buys metal fresh through a dealer.
- New or unusual products. Mints release new bullion series regularly. If a product is not on your custodian's established list, ask the custodian for written confirmation of eligibility before the purchase settles.
- Fractional coins. Smaller sizes (half, quarter, tenth ounce) of eligible coins generally qualify, but premiums per ounce run higher on fractional sizes, so the same cost questions apply.
Custodians maintain their own approved-product lists and will decline items that create doubt, which is a feature rather than an obstacle. How that gatekeeping role works is covered in What a Gold IRA Custodian Does and How to Vet One.
The Bottom Line
The eligible universe is smaller than dealer catalogs suggest but larger than you need: Gold Eagles, Gold Buffalos, Maple Leafs, Philharmonics, Kangaroos, Silver Eagles, and accredited-refiner bars cover the practical choices for most accounts. The main points to double-check are the Krugerrand and other 91.67% coins without a statutory exception, anything numismatic or slabbed, and high-premium proofs that qualify legally but cost more per ounce than standard bullion. When in doubt, get eligibility confirmed in writing by the custodian, not just the dealer, before the purchase settles.
