The U.S. Mint introduced the American Buffalo in 2006 as its first-ever .9999 fine (24-karat) gold coin — a genuinely new milestone, since every prior U.S. gold coin, including the Gold Eagle, was struck at a lower alloyed purity. Its design reuses James Earle Fraser's Buffalo nickel from 1913, widely considered one of the most iconic coin designs in American numismatic history, placing a Native American portrait on the obverse and an American bison on the reverse. The Buffalo was authorized by the Presidential $1 Coin Act of 2005 specifically to give the U.S. Mint a purer-gold competitor to already-established 24-karat coins like the Canadian Gold Maple Leaf and Chinese Gold Panda, which had been drawing bullion buyers who wanted maximum purity rather than the Gold Eagle's harder 22-karat alloy.
Unlike the Gold Eagle's four-size lineup, the Buffalo is a single-size coin — 1 oz only — for every year except 2008, when the Mint issued fractional sizes (1/2 oz, 1/4 oz, 1/10 oz) as a one-time experiment before discontinuing them permanently. This makes a size-complete Buffalo collection a fundamentally different, much smaller project than a Gold Eagle collection: one date run of 1 oz coins, plus an optional closed sub-collection of the four 2008 sizes for anyone chasing that specific one-year-only set. New buyers should decide upfront whether they're just accumulating 1 oz coins for gold exposure or specifically chasing the 2008 fractional set — the second is a meaningfully pricier, more patience-testing project.
The dates serious Gold Buffalo collectors specifically chase — the rest of the run trades close to melt value.
First year of issue, and the first time the U.S. Mint had ever struck a .9999 fine 24-karat gold coin — every American Gold Eagle before and since is a lower-purity 22-karat alloy, which is the Buffalo's core differentiator from its Eagle stablemate.
The only year the Mint issued fractional Buffalo sizes (1/2 oz, 1/4 oz, and 1/10 oz) alongside the standard 1 oz — fractional Buffalo production was discontinued after 2008 and never resumed, making that single year's fractional coins a closed, one-year-only sub-collection within the series.

Start tracking freeYes — the Buffalo is .9999 fine (24-karat), while the Gold Eagle is 22-karat (91.67% gold) alloyed with silver and copper. The Buffalo was the U.S. Mint's first-ever 24-karat gold coin when it launched in 2006.
Primarily 1 oz only. The Mint issued fractional sizes (1/2 oz, 1/4 oz, 1/10 oz) exclusively in 2008 before discontinuing them — those four 2008 coins form a distinct, closed sub-collection rather than an ongoing size lineup.
To compete directly with already-established 24-karat coins like the Canadian Gold Maple Leaf and Chinese Gold Panda — bullion buyers who wanted maximum purity had been going to those coins instead of the lower-purity Gold Eagle.
