American Gold Coins encompasses gold coinage produced by the United States Mint, including the Gold American Eagle and Gold Buffalo series. Listings in this category span multiple weights and years, from random-year bullion pieces to current-dated issues, across both fractional and one-troy-ounce denominations. The Gold American Eagle, authorized by the Gold Bullion Coin Act of 1985, carries Augustus Saint-Gaudens' Liberty obverse design and a family-of-eagles reverse. It is struck in 22-karat gold (.9167 fine) and issued in four standard weights: 1 oz, 1/2 oz, 1/4 oz, and 1/10 oz. The Gold Buffalo, introduced in 2006, features James Earle Fraser's iconic Buffalo Nickel design and is struck in 24-karat gold (.9999 fine), available in the 1 oz denomination. Both series are legal-tender U.S. coins and among the most widely recognized gold coin programs in the world.

Frequently asked questions
The Gold American Eagle is struck in 22-karat gold (.9167 fine) and features Augustus Saint-Gaudens' Liberty design on the obverse. The Gold Buffalo is struck in 24-karat gold (.9999 fine) and displays James Earle Fraser's Buffalo Nickel design. The Eagle is available in four weights; the Buffalo is issued as a 1 oz coin. Both are produced by the U.S. Mint and are legal-tender coins.
Gold American Eagles are issued in four standard weights: 1 oz (face value $50), 1/2 oz ($25), 1/4 oz ($10), and 1/10 oz ($5). Each denomination contains its stated weight in gold, with the total coin weight slightly higher due to the 22-karat alloy. All four sizes are commonly available on CoinDuffle, both as specific dated issues and as random-year bullion pieces.
A 'random year' listing means the dealer ships a coin from their existing inventory without guaranteeing a specific mint year. The coin meets all standard specifications for the series — correct weight, fineness, and design — but the date on the coin is determined by available stock at the time of fulfillment. Specific-year listings, such as a 2026-dated coin, guarantee that exact date.
The Gold Buffalo is struck in .9999 fine (24-karat) gold, making it one of the purest gold coins produced by the U.S. Mint. Each 1 oz coin contains exactly one troy ounce of gold. This high fineness distinguishes the Buffalo from the Gold American Eagle, which uses a 22-karat (.9167 fine) alloy that includes copper and silver for added durability.
