The American Gold Buffalo is a special coin in two respects. First, it is struck in .9999 (24-karat) gold. This is the same level of purity found in the Canadian Gold Maple and Australian Gold Kangaroo. Secondly, it features the iconic Buffalo design first employed on the 1913-1938 5c Nickel. Thanks to its beautiful design and industry-leading purity, the Gold Buffalo has developed a strong worldwide following.
