In 1912, James Fraser designed the Buffalo Nickel. He designed both the obverse and the reverse. These coins were first struck on February 22, 1913, but they weren't put into circulation until March 4th, 1913. Proof coins were made from 1913 to 1917 for collectors. They were in circulation from 1913 to 1938 and were minted in Philadelphia, Denver, and San Francisco. Ultimately, it was replaced by the Jefferson Nickel.  There are 2 varieties which are straight ground and the other is a little mound on which the buffalo stands. The Buffalo Nickel is 75% nickel and 25% copper. It is a really interesting coin and is not particularly expensive. The name of the buffalo on the reverse was Black Diamond and he lived in the Central Park Zoo.  The Native American on the obverse is a combination of three Native Americans. ( Thanks Mike). In my collection, I have a 1930 S, 1935 D, 1936, and a 1937 D nickel. They minted approximately 1,212,995,919 through the 25 years it was around. There are about 64 different types of coins from mintmarks, dates, and major varieties.
