The American Buffalo is the first 24-karat gold coin ever issued by the U.S. Mint. Introduced in 2006, it contains 1 troy oz of .9999 pure gold. The design features a Native American portrait on the obverse and an American bison on the reverse, both adapted from James Earle Fraser’s classic 1913 Buffalo nickel. Backed by the U.S. government, it's a premium option for investors seeking maximum gold purity.
