I have what I belive is a slot coin, thete is no denomination on it, the wt. is 1 oz and it is metal. Around the rim on one side it says redeemable only at Harvey's resort hotel-casino Stateline Nevada, on the other side it says Lake Tahoe's first luxury hotel-rise hotel. In the middle of one side is a picture of the hotel, the other side has a wagon wheel/skull with a date of 1966. Any information will be greatly appreciated.
