Buffalo nickel
The 1940s, 1950s, 1960s and 1970s were a transitional period for hobo coin engravers, during which the Buffalo nickel was gradually replaced by the Jefferson nickel. Some veteran nickel carvers such as Bo and Bert continued making hobo nickels in the classic old style. Bo, in fact, did his best work in the early 1950s, when he carved many spectacular cameo portrait hobo nickels.
