The proof $50 American Buffalo is generally sold as an individual coin, though proof issues have been included in special collector sets over the years. One notable case in which the Buffalo gold coin was sold in a set was in 2008; that is when a special four-piece American Buffalo gold coin set offered by the United States Mint brought together a proof $50 American Buffalo gold coin with one-year-only Buffalo gold coins in tenth-ounce ($10), quarter-ounce ($25), and half-ounce ($50) sizes.
American Buffalo gold coins are sought-after by coin collectors who like the marriage of a 24-karat gold coin with a time-honored design, as is the case with these bullion issues. The Buffalo gold coins reboot the classic Indian Head or ?Buffalo? designs by James Earle Fraser. The designs, which appeared on the nickel from 1913 through 1938, are recognizable not only by coin collectors but also many non-numismatists who grew up using five-cent nickels with Fraser?s ?Buffalo? design, which has also made countless cameo appearances in popular art, on various television shows, and in movies.
