The Silvertowne 10oz Silver Bar with a Buffalo design interprets a very classic and historical design on a very modern piece. The American Buffalo has been used time and time again on bullion pieces. It resembles the famous design by James Earle Fraser for the Indian Head Nickel issued in 1913. There have been several renditions of the American Buffalo design but all of them allow the Indian and the Buffalo to be featured. The Buffalo is thought to be a bison that was popular in the New York City Central Park Zoo named Black Diamond. Legend has it that Frasier has a zoo keeper distract the buffalo in order to get a quick sketch of the beast.
