About Graded Gold Buffaloes (BU)

Graded Gold Buffaloes (BU) brings together certified Brilliant Uncirculated examples of the American Gold Buffalo — the United States Mint's flagship 24-karat gold coin series, first issued in 2006. Each coin in this category has been graded and encapsulated by a recognized third-party grading service (PCGS or NGC), with numeric grades typically ranging from MS-69 to MS-70, providing a standardized, objective assessment of surface quality and strike.

The American Gold Buffalo is struck in .9999 fine (24-karat) gold, making it one of the purest gold coins produced by a sovereign mint. The obverse reproduces James Earle Fraser's iconic Native American portrait and the reverse his American bison design — imagery originally introduced on the 1913 Buffalo Nickel. The standard issue is the 1 troy oz denomination with a $50 face value, though the U.S. Mint has periodically offered fractional sizes (½ oz, ¼ oz, and 1/10 oz) in select years.

On Lone Star Coins, this category spans multiple production years from 2006 to the present, with listings from a range of vetted dealers offering coins in various certified grades. Buyers will find both raw-to-slab upgrades and coins graded directly from original Mint packaging, across the MS-69 and MS-70 grade points that dominate the certified BU population. Whether sourcing a specific date for a year-set registry, filling a grade-run, or adding a high-grade example to a type collection, this page covers the breadth of certified BU Gold Buffalo inventory available on the marketplace.
