The short answer
The American Gold Buffalo is a 1 oz coin of 24-karat, 99.99% pure gold, made by the U.S. Mint since 2006. Its design comes from the 1913 Buffalo nickel. It’s allowed in a gold IRA because its purity meets the IRS standard for bullion. Next to the Gold Eagle, it’s purer and softer, and investors can buy it in one size only.

What it is
Congress authorized the Buffalo in the Presidential $1 Coin Act of 2005, and the Mint launched it in 2006. Unlike the 22-karat Gold Eagle, the Buffalo is 24-karat gold. Each coin contains one troy ounce of .9999 fine gold and carries a $50 face value, which is symbolic. The coin is worth what its gold is worth, plus a premium.
In 2008, and only that year, the Mint also made 1/2 oz, 1/4 oz and 1/10 oz Buffalos. They’re collector pieces now and usually sell for more than their gold value. The Mint has also listed a 2026 anniversary 1/10 oz coin for collectors, due to go on sale in December 2026.
The design
The Buffalo reuses James Earle Fraser’s design for the 1913 Buffalo nickel. The front shows a Native American in profile, and the back shows an American bison standing on a mound. Fraser had studied under Augustus Saint-Gaudens, whose Liberty is on the Gold Eagle, so both U.S. gold bullion coins carry designs from the early 1900s.
Can a Gold Buffalo go in an IRA?
Yes, by a different route from the Eagle. The tax code lets an IRA hold gold bullion that meets the purity required for delivery on a regulated futures contract, which for gold is 99.5%. At 99.99%, the Buffalo clears that easily.
As with any IRA metal, the coins have to be held by the trustee or custodian, not by you. The gold IRA guide covers the rules, and gold IRA fees covers what the account will cost.
Gold Buffalo vs. Gold Eagle
| Gold Buffalo | Gold Eagle | |
|---|---|---|
| Purity | 24 karat, 99.99% | 22 karat, 91.67% |
| Pure gold in the 1 oz coin | 1 troy oz | 1 troy oz |
| Sizes for investors | 1 oz | 1 oz, 1/2 oz, 1/4 oz, 1/10 oz |
| Durability | Softer, scratches more easily | Harder alloy, holds up better |
| IRA route | Meets the bullion purity test | Named in the tax code |
| First issued | 2006 | 1986 |
Both hold the same gold and both sell easily in the U.S. The Eagle’s small sizes suit people who want to buy a little at a time, and the Buffalo suits buyers who prefer pure gold. Premiums move around, so compare the two on the day you buy.
Handling a 24-karat coin
Pure gold scratches and dents more easily than 22-karat gold. A scratch doesn’t change the gold content, but dealers look harder at damaged coins, and heavily marked ones can fetch less. Hold coins by the edges, keep them in their tubes or capsules, and don’t clean them.
Price and resale
Like other bullion coins, the Buffalo sells for the spot price of its gold plus a premium that covers minting, distribution and the dealer’s margin. The Mint sells bullion Buffalos only to its authorized purchasers, so you buy them from dealers, and U.S. dealers buy them back readily.

When you sell at a profit, the IRS taxes the gain as a gain on a collectible: up to 28% for coins held more than a year, and ordinary income rates for coins held a year or less.
Proof Buffalos
The Mint sells proof Buffalos directly to collectors, with a “W” mint mark, mirror-like backgrounds, a presentation box and a certificate. They cost well above their gold value. Unless you’re collecting, the bullion coin is the better buy, and our guide to proof vs. bullion coins explains why the extra is hard to recover.
Frequently asked questions
Is the Gold Buffalo pure gold?
Yes. It’s .9999 fine, which is 24 karat, and it contains one troy ounce of gold.
Can I buy Gold Buffalos from the U.S. Mint?
Only the proof and collector versions. Bullion Buffalos go to the Mint’s authorized purchasers, and you buy them from a dealer.
Is the Gold Buffalo a good investment?
It’s a convenient way to own a known amount of gold, and its value moves with the gold price. Whether gold belongs in your savings at all is a separate question, which we look at in is gold a safe investment?
Are 2008 fractional Buffalos worth more than their gold?
Usually, because they were made for one year only and collectors want them. That extra value depends on collector demand, so price them with a coin dealer rather than on melt value alone.
