Hobo Nickel Art Coin

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.
