1 oz American Buffalo Gold Coin | 2026

The 2026 1 oz American Buffalo Gold Coin (also sold as the American Gold Buffalo) is a $50 bullion coin and US legal tender (an official US coin), struck by the United States Mint in 24-carat gold (999.9 fine, or 99.99% pure). Each coin contains one troy ounce (31.1035 g) of pure gold and carries James Earle Fraser’s Buffalo nickel design. It is priced on the live gold price plus a premium, and fully insured delivery is included in the price for private customers. StoneX Bullion also offers a buyback service.

For UK buyers: investment gold coins are VAT-exempt, but the American Buffalo is not exempt from Capital Gains Tax.

Design: Fraser’s Buffalo nickel in 24-carat gold

The obverse shows a right-facing Native American profile with the inscription LIBERTY, the date 2026 and the designer’s initial F. The reverse shows an American bison with the inscriptions UNITED STATES OF AMERICA, E PLURIBUS UNUM, IN GOD WE TRUST, $50, 1 OZ. and .9999 FINE GOLD. The coin has a reeded (finely grooved) edge, a diameter of 32.70 mm, a thickness of 2.95 mm and a total weight of about 31.1 g.

James Earle Fraser created both designs for the Buffalo nickel, issued from 1913. The bison is reputedly modelled on Black Diamond, a bison kept at a New York zoo. Because the coin is pure gold, its surface is softer than a 22-carat coin’s and can mark more easily, so a 33 mm coin capsule is worth considering.

Which 2026 American Buffalo is this?

This is the standard 2026 bullion coin, made for investors and never used as money (dealers call this condition Brilliant Uncirculated, or BU). It is not the 2026-W Proof, the collector version the US Mint issued for the 250th anniversary of the United States with the dates 1776 ~ 2026 (US Mint announcement). This coin shows the single date 2026. 2026 also marks 20 years since the American Buffalo series launched in 2006.

VAT and Capital Gains Tax for UK buyers

VAT: HMRC treats a gold coin as investment gold, and therefore VAT-exempt, if it was minted after 1800, is at least 900 thousandths fine, is or has been legal tender in its country of origin and is normally sold at no more than 180% of its gold value. The American Buffalo fits this description (see HMRC VAT Notice 701/21A). More in our guide to VAT on gold and silver bullion.

Capital Gains Tax: HMRC treats coins as currency only if they are legal tender, and foreign-currency coins are chargeable assets (see HMRC Capital Gains Manual CG78305). The American Buffalo is US legal tender, so, unlike the Gold Britannia and Sovereign, it is not exempt from Capital Gains Tax. Browse CGT-free gold coins.

This is general information, not tax advice.

Price and premium

The price is the live gold price plus a premium that covers minting, logistics and trading. The premium is shown next to the price and reduces for larger quantities. When comparing dealers, compare the premium over the gold price, not just the headline price.

American Buffalo, American Eagle or Gold Britannia?

All three contain one troy ounce of gold. The Eagle is alloyed with copper and silver, which makes it heavier and harder-wearing; the Buffalo is the purer coin. See the 1 oz American Eagle Gold Coin 2026 and our Gold Britannia range.

Who this coin suits, and who it may not

• Suits: buyers who want a 24-carat, 1 oz US coin with a recognisable design, and who are comfortable with its Capital Gains Tax treatment.
• May not suit: UK buyers whose priority is CGT-free gold (consider the Britannia or Sovereign), buyers who want the 250th-anniversary markings (those are on the 2026-W Proof coin), and buyers who will handle the coin often, because pure gold marks easily.
