I humbly submit that I believe this to be what is referred to as a "Bezel Coin". Someone ground it down around the rims on both sides in order to fit it into a bezel to make jewelry. This type of jewelry is often created for a particular birth year. Just my opinion, you'll probably want to wait for the experts to chime in, I most definitely could be wrong.
