The buffalo nickel coin was minted using soft metal & was imprinted with the portrait of an indian with bold features, making it easier to deface & transform into the portraits of other people, animals, or even scenery. Hobos at the turn of the 20th century often carved and traded the coins hence the name... Now many modern artists still carry on the tradition of carving these coins. I like the more traditional portrait mutation concept rather complete transformation of the coin something else
