I think they sell these at buckskinner rendezvous. The back of side of the coin shows probably a number for a year, as in Japanese coins they will give a two digit number and then that represents a particular year. If I can remember my Asiatic numbers I think this number is 20( || + ) just below the dragon, but don't quote me on that...or any of this for that matter. Hmm, the number could be a denomination or something too, but, if they are 'fantasy' coins, maybe they are only intended for that, or commemoration only.
