Hobo Nickel Art Coin

During this time period, hobo-style coin alteration could be found outside the United States, primarily in Britain, France, and South Africa.
The Buffalo nickel
When the Indian Head, or Buffalo nickel, was introduced in 1913, it became popular among coin engravers. The big Indian head was a radical departure from previous designs and would not be seen on any subsequent coins. The large, thick profile gave the artists a larger template to work on and allowed for finer detail.
