40X Coin Mixed Date Indian Head Buffalo Nickel Roll 1910's-1930's Nice Full Date Roll (Dates Selected at Random) The Native American depiction on the coins obverse is believed to be based on three different American Indians. Two of the American Indians who modeled for Fraser as he sculpted the coin were named by the designer before his death. They were Chief Iron Tail of the Lakota Sioux and Chief Two Moons of the Cheyenne. Although many have claimed to have had a sitting with Fraser for this design, he could not recall the name of the third person, and satisfactory documentation has not yet been found to identify that individual. It is widely believed that the bison on the coin's reverse was modeled after Black Diamond, a popular attraction at the New York Zoological Gardens. In the first year of the coin's issue, 1913, there were two distinct varieties, the first showing the bison on a mound (pictured above) and the second with the base redesigned to a thinner, straight line. Matte proof coins were struck and made available to collectors from 1913 to 1916. The designer's initial, the letter ‘F,' appears on the obverse below the date.
