Hobo Nickel Art Coin

Later old hobo nickels (1940–1980)
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.
During this 40-year period, many new carvers appeared, and style and subject matter became decidedly modern. Subjects became more ethnically and socially diverse (e.g., a Chinese woman with triangular hat, hippies with long hair and glasses, men wearing floppy hats, etc.). Some of these new artists used new techniques such as power engravers, vibrating tools, and felt marker pens to add color to hair.
By the end of the 1970s, most Buffalo nickels had disappeared from circulation, and the majority of engravings were performed on worn coins. Bo, for example, was forced to obtain Buffalo nickels from coin dealers, some of whom commissioned carvings.
