Adding a little:
Patriotic Civil War Tokens were struck by private die sinkers and merchants in order to make up for the lack of circulating coinage during the war. These tokens were mostly issued in the Northeast and Midwest, and often feature pro-Union themes or slogans. This particular variety was struck in 1863 and has been designated F-82/351a by the declarative reference on this subject, Patriotic Civil War Tokens by George and Melvin Fuld. As designated by the "a" at the end of the Fuld number, this variety is struck in copper.
