Please check again and post a new question. Buffalo* nickels
were minted from 1913 to 1938, and in any case the US didn't mint
any nickels until 1866.
[*] Nickels depicting an Indian head on one side and a buffalo
on the other are called Indian head nickels OR buffalo nickels, but
not "buffalo head" nickels because they show the entire buffalo,
not just its head.
