These were definitely not sold in the casino's stores...in fact, I don't believe Artichoke Joe's even has a store...just a restaurant and bar. They were given out to their best customers at Chinese New Year's. No markings, but it sure looks like the silver in a typical silver strike, and not like the IGT Palms commerative coins. True, not from a machine, but probably as much a silver strike as the Club's 5th anniversary.
