I bought this from a friend along with some PAC MAN tokens that I wanted. Got em dirt cheap. I've no idea what it is other than a 2008 date. The iPhone pics aren't great I know. Sorry. Thanks for any advice.

Thanks so much for the info. I'm new and I've learned alot just reading on this site. You folks are well informed and have helped me so much. I guess this isn't the one that's gonna put me on easy street but it is a very nice looking coin for the collection and another learning experience. (Wish it was silver but...) Again, thanks and I hope I can repay the favor sometime. Mark
