I was wondering about the fact mine has all the tack marks but not this one. Im on a mission to find out what this is, the park we found it in had a festival opening day about 20 years ago, could it be a token from a traveling carnival? I did a google search and it pulled up "10" and I have no idea why, and this is my first good find so Im very interested in finding out the truth on it even if its from a game hahah
