What Is Bullion: The One-Sentence Answer
Quick Answer
Bullion is precious metal (gold, silver, platinum, or palladium) valued by weight and purity rather than collector appeal. Under IRC §408(m)(3), IRAs may hold bullion that meets IRS minimum purity thresholds. Collectibles that fall outside those thresholds are prohibited and trigger a taxable distribution if purchased inside a retirement account.
Gold, silver, platinum, and palladium qualify as bullion when their market value tracks spot price, not numismatic appeal. IRC Section 408(m)(3) lets a self-directed IRA hold bullion meeting IRS purity floors of 99.5% for gold (with a statutory carve-out for the American Gold Eagle at 91.67%), 99.9% for silver, and 99.95% for platinum and palladium. Collectibles fall outside those thresholds and trigger ordinary income tax plus a 10% penalty under age 59 and a half if held inside an IRA.
The word “bullion” comes from the Old French billon, a term for base metal, and settled into its modern meaning over centuries: a standardized precious metal product priced at or near the spot price of the metal it contains. You pay for the metal, not for its age, rarity, or condition. That simple principle is what separates bullion from collectible coins in the eyes of the IRS.
Three Physical Forms Bullion Takes
Bullion shows up in three shapes, each with different cost profiles and storage footprints.
Bars. The most cost-efficient option for holding large quantities. Produced by recognized refineries such as the Royal Canadian Mint, Valcambi, and PAMP Suisse. A 10 oz gold bar carries a lower per-ounce premium than ten individual 1 oz coins because fabrication costs spread across more metal. Bars stack neatly, which lowers storage costs. The tradeoff: large bars are harder to sell in partial quantities.
Coins. Government-issued, legal-tender coins from recognized national mints. The American Gold Eagle, American Gold Buffalo, Canadian Gold Maple Leaf, and Austrian Gold Philharmonic are common IRA-eligible examples. Coins typically carry a 4-9% premium over spot on a 1 oz gold piece because of their certification, legal-tender status, and broader retail recognition. They are easier to sell in smaller increments than large bars.
Rounds. Private-mint products that resemble coins but carry no legal-tender face value. A silver round from a US private refinery may meet the same 99.9% purity standard as a government coin while carrying a lower premium. Rounds can qualify for IRA inclusion if they meet purity thresholds. By definition, they are never numismatic collectibles because they carry no collector-grade designation.
How the IRS Draws the Line Between Bullion and Collectibles
This is where investors most often get confused. A coin can be bullion or a collectible depending on whether it meets IRS purity standards and whether its market price is driven primarily by metal content or by collector demand.
The base rule: IRC §408(m)(1). An IRA that acquires a collectible is treated as having taken a distribution equal to the cost of that collectible. That means ordinary income tax in the year of the transaction. If the account holder is under 59½, a 10% early withdrawal penalty applies as well. The collectible remains in the account but is no longer treated as an IRA asset for tax purposes. No cure exists after the fact.
The exemptions: §408(m)(2) and §408(m)(3).
- §408(m)(2) carves out specific government-issued coins by name: US gold, silver, platinum, and palladium coins issued under federal law, plus certain state-issued coins. The American Gold Eagle is explicitly listed here even though its gold fineness (91.67%) falls below the generic bullion threshold.
- §408(m)(3) covers bullion that meets minimum purity standards. One additional requirement applies under this subsection: the bullion must be in the physical possession of a qualified trustee or IRA custodian, not in your home.
A 19th-century US gold coin appraised at several times its melt value is a collectible. The metal it contains does not redeem it. Its price is driven by rarity and condition, and the IRS classifies it accordingly. The rule is categorical, not proportional.

IRS Purity Thresholds for Each Metal
Source: IRS Publication 590-A and the text of 26 U.S.C. §408(m). These thresholds have not changed since Congress enacted them as part of the Taxpayer Relief Act of 1997.
Why Home Storage of IRA Bullion Is Not Permitted
§408(m)(3)(B) is explicit: bullion held under that subsection must be in the physical possession of a trustee. A qualified IRA custodian (a bank, credit union, or IRS-approved non-bank trustee) satisfies this requirement. Your home safe does not. A bank safe deposit box rented in your own name does not either, because you retain personal access.
If you take personal delivery of IRA-owned bullion, the IRS treats the full value as distributed at the time you receive it. Income tax applies that year. The 10% penalty applies if you are under 59½.
Several promoters sell “home storage gold IRA” arrangements using an LLC structure as a workaround. The IRS has challenged these structures in court, and FINRA flags home-storage IRA pitches as a common fraud red flag in its investor alerts. If a salesperson leads with the ability to keep your gold at home inside an IRA, that is a warning sign worth taking seriously.
What Bullion Costs Beyond the Spot Price
The spot price is what the metal trades for on wholesale markets at a given moment. The premium is what you pay above that. For IRA-eligible bullion, typical premiums in early 2026 run approximately:
- Gold bars (1 oz): 2-5% over spot
- American Gold Eagle (1 oz): 5-9% over spot
- American Gold Buffalo (1 oz): 4-8% over spot
- Silver American Eagle (1 oz): 15-25% over spot (silver premiums are structurally higher due to industrial demand cycles)
Premiums vary with demand, supply constraints, and market events. They represent a real cost of ownership because you do not recover them dollar-for-dollar on the sell side. When evaluating a Gold IRA provider, ask for a specific product list with premiums disclosed before you commit. A company that walks you through costs transparently before you open an account is generally a better counterpart than one that presents pricing only after you have signed paperwork.

Frequently Asked Questions
Is all gold considered bullion?
No. Gold jewelry, decorative items, and numismatic (collector) coins are not bullion. Bullion refers specifically to gold products priced at or near the current spot rate based on weight and purity. A collector coin that commands a premium due to historical rarity or high condition grades is a collectible under IRS rules, regardless of its underlying gold content.
Can I hold any coin in a Gold IRA?
No. Only coins that meet IRS criteria qualify. Government-issued coins explicitly named in IRC §408(m)(2), such as the American Gold Eagle, American Silver Eagle, and American Gold Buffalo, are permitted. Certain foreign government coins, including the Canadian Gold Maple Leaf and Austrian Gold Philharmonic, qualify under §408(m)(3) because they meet the 99.5% gold purity threshold. Rare collector coins and most privately minted coins do not qualify. Your IRA custodian can provide a complete approved-product list for their platform.
What is the difference between bullion coins and proof coins?
Proof coins are struck multiple times using polished dies, producing a mirror-like finish. They are sold in presentation packaging and carry premiums well above the spot price of the metal they contain. Most proof coins are classified as collectibles for IRA purposes because their price reflects their presentation quality, not just their metal. A small number of proof coins from recognized government mints may meet purity standards and qualify, but standard bullion coins are the simpler, lower-risk choice for an IRA. Check with your custodian before acquiring any proof coin for a retirement account.
Why does the American Gold Eagle qualify if it is only 91.67% gold?
Congress carved it out by name in IRC §408(m)(2). The American Gold Eagle falls below the 99.5% threshold required under §408(m)(3) for generic bullion, but lawmakers chose to include it explicitly when drafting the legislation. The coin does contain exactly 1 troy oz of pure gold per the US Mint’s specification; the copper and silver alloy is added purely for durability. The statutory carve-out means the purity threshold does not apply to this specific coin.
What happens if my IRA accidentally buys a collectible?
The IRS treats the acquisition as a deemed distribution equal to the cost of the collectible at the time of purchase. You owe ordinary income tax on that amount in the year of the transaction. If you are under 59½, a 10% early withdrawal penalty also applies. The purchase does not disqualify your entire IRA, but the specific amount spent is taxed and penalized as if you had withdrawn cash. This is why using a custodian with a pre-screened product list matters: it removes the compliance burden from you.
Is silver bullion treated the same as gold bullion in an IRA?
The same legal framework applies. Silver bullion at 99.9% purity (0.999 fine) qualifies under §408(m)(3). The American Silver Eagle is named in §408(m)(2). The same custodian-possession requirement applies: IRA-owned silver must be stored at an IRS-approved depository. The main practical difference is that silver’s lower price per ounce means larger physical volumes for an equivalent dollar value, which increases storage weight and can affect custodian storage fees. Consult your tax advisor for specifics on your situation.
Can I transfer bullion I already own into a Gold IRA?
Generally, no. In-kind contributions of physical bullion into an IRA are not permitted under current IRS rules. You fund a Gold IRA with cash (from a rollover, transfer, or annual contribution), and the custodian then purchases IRS-approved bullion on your direction, with the metal shipping directly to an approved depository. If you already own physical bullion outside a retirement account, you cannot simply hand it to a custodian and treat it as an IRA contribution. Consult your tax advisor for your specific situation before attempting any transfer.
Does the IRS approve specific bullion dealers?
The IRS approves custodians and depositories, not individual dealers. It does not maintain a published list of approved precious metals dealers. The practical check is whether the bullion itself meets the purity requirements in IRC §408(m) and whether the transaction flows through an IRS-approved custodian. Many custodians maintain their own approved-dealer lists for operational reasons. Augusta Precious Metals, Birch Gold Group, and Noble Gold Investments each work with established custodians and provide their own product catalogs.
