When Tualatin and Portland-area buyers want the purest gold coin the United States Mint strikes for the public, the conversation often turns to the American Gold Buffalo. First issued in 2006, it was the Mint’s first .9999 fine 24-karat gold bullion coin for investors, and Local Coin Company lists a one-ounce Gold Buffalo on its gold page alongside Eagles, Maple Leafs, and Krugerrands.

This guide covers what a Gold Buffalo is, widely published weight and purity specs from the U.S. Mint, why the price differs from spot, how Buffalos compare with American Gold Eagles and other popular gold, and what to check before you buy locally. It is educational, not a gold-price forecast.

What an American Gold Buffalo Is

The American Gold Buffalo (often called a Gold Buffalo) is a United States Mint bullion coin whose weight, content, and purity are guaranteed by the U.S. government. The design adapts James Earle Fraser’s classic 1913 Buffalo / Indian Head nickel: a Native American portrait on the obverse and an American bison on the reverse. Market value follows gold content plus the dealer premium. The stamped face amount of fifty dollars is legal tender, but it is symbolic next to the metal value.

According to the U.S. Mint’s American Buffalo bullion page, these are investment-grade coins containing one troy ounce of .9999 fine 24-karat gold.

Purity, Weight, and Size

Unlike the American Gold Eagle’s 22-karat alloy, the Gold Buffalo is .9999 fine gold—about 99.99 percent pure, or 24-karat. Many buyers choose it when they want U.S. Mint gold at Maple Leaf-level fineness.

Widely published U.S. Mint specifications for the standard one-ounce bullion coin include:

• Gold content — 1.0000 troy ounce (31.1035 grams) of pure gold
• Gross weight — about 1.0001 troy ounce (31.108 grams)
• Diameter — 32.70 mm (1.287 inches)
• Thickness — about 2.95 mm (0.116 inches)
• Edge — reeded
• Face value — fifty dollars (legal tender)

The Mint currently focuses bullion production on the one-ounce denomination. Fractional Buffalos were struck in limited years historically (notably 2008); do not assume fractionals are routinely available the way fractional Eagles often are. Soft-touch: confirm what is in the case when you visit.

Local Coin Company’s live gold board lists a one-ounce Gold Buffalo sell quote. Soft-touch: refresh those quotes when you are ready to trade; availability and ask prices move.

Why the Price Differs From Spot

Spot is the wholesale reference for one troy ounce of gold for near-term delivery. A finished Gold Buffalo almost never sells at exact spot. The amount above spot is the premium: minting, distribution, insurance, handling, and the dealer’s margin. Soft-touch rule: treat any spot number you see online as a snapshot. Confirm the live ask when you are ready to buy or sell.

Buffalos often trade at a somewhat different premium than American Gold Eagles of the same ounce size because purity, demand, and minting economics differ. Compare like with like—one-ounce bullion Buffalo to one-ounce bullion Buffalo—rather than mixing proof specials or private rounds into the quote.

Buffalos vs Eagles, Maple Leafs, and Bars

Each product solves a different problem:

• American Gold Buffalos — U.S. Mint .9999 fine 24-karat gold; one-ounce bullion focus; Fraser buffalo design; high purity appeal.
• American Gold Eagles — U.S. Mint 22-karat alloy (gold with silver and copper); each size still contains its full stated pure-gold weight; four common sizes. See American Gold Eagle: What Buyers in Tualatin Should Know.
• Canadian Gold Maple Leafs — .9999 fine gold from the Royal Canadian Mint; different look and series. See Canadian Gold Maple Leaf: What Buyers in Tualatin Should Know.
• Gold bars (for example 1 oz, 10 oz, or kilo bars from known refiners) — often lower premium per ounce and denser storage, but less divisible than fractional coins.

When you compare quotes, match size and finish (bullion versus proof) so you are not pricing different products against each other. Proof Buffalos and special editions can carry collector premiums that do not apply to ordinary bullion.

What Buyers in Tualatin Should Check

Before you commit, ask for today’s ask on the same product you want—typically a one-ounce bullion Gold Buffalo—and compare it with live offerings on the gold page. Confirm condition (brilliant uncirculated bullion versus proof), year if that matters to you, and whether the quote is for a single coin or a larger order.

Buying Tips That Save Headaches

• Compare the same coin to the same coin—bullion Buffalo to bullion Buffalo—not a Buffalo to a private round or a proof special.
• Ask how the buyback works if you sell later; spreads are normal in physical gold. See How to Sell Gold and Silver in Tualatin, Oregon.
• Have a storage plan before you leave with metal. See How to Store Gold and Silver Safely at Home.

FAQ

Is a Gold Buffalo pure 24-karat gold?
Yes. The standard American Gold Buffalo bullion coin is .9999 fine gold (24-karat), per U.S. Mint specifications. That differs from the American Gold Eagle, which is a 22-karat alloy that still contains its full stated pure-gold weight.

Does a Buffalo come in fractional sizes like the Eagle?
The Mint’s ongoing bullion program centers on the one-ounce coin. Fractional Buffalos appeared in limited earlier years; availability today is not the same as fractional Eagles. Ask the shop what is in stock.

Bottom Line

The American Gold Buffalo is a U.S. Mint .9999 fine 24-karat gold bullion coin, best known as a one-ounce piece with the classic Fraser buffalo design. You pay spot plus a premium, compare products carefully, and buy from a dealer you trust. For Tualatin and Portland-area buyers who want to see the metal first, a shop visit keeps the decision concrete.
