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.

Worth about $1 (shipped) on eBay (at least the 2 listings that actually sold). Exchange rate of ~$0.05 (from what I could find).

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
