I have just been given a silver strike that I am not able to identify (and can't find it listed in any of my reference books). It is a $10 strike, 999 outside with GRAND CASINO 1996 on the logo side, and the Marilyn Monroe caricature "Hollywood Classic" on the design side. No city/state is listed, nor does it have a mint mark thatI can find. Does anyone know anything about this strike?
