This issue is considered a medal, as opposed to a token. Tokens were intended to circulate as money substitutes. The medals were often, but not always, holed to be worn.
This appears to be made of white metal. Political medals were listed by DeWitt, and this one looks to be his catalog # GMcC 1864-14, 31mm.
Here's a damaged example that's now for sale on
ebay ....

ebay medal, also damaged, is in much better condition than the subject piece. Collectors of these early medals generally avoid buying damaged medals at, or even near, this price level.
The raised, granular surfaces on the subject piece causes me to suspect that it's a copy or else has suffered environmental damage like intense heat, perhaps. Many copies of Civil War tokens and medals were produced in the 1960's, during the centennial years of the war. Note that this was prior to enactment of the 1973 Hobby Protection Act which demanded that copies be marked as such.
