I have a token that I didn't know what it was. I wasn't sure if it was a Civil War Token or what...

It's part of my coin collection and for year's I thought it was nothing until I started looking through my BlackBook Price Guide to U.S. Coins today looking for what it could be. I came across the section on Civil War Tokens. Then I found your site and you have an image of the very coin I have! What can you tell me about this Token? (See Attached Images) The center is missing and I noticed it was missing on yours too, so I don't know what was there at one time.
