Ive got what might be a pre fire chip from the overland casino here in Pioche, from what i have read no known examples exist but this differs from all other known chips as it dosnt have the middle initial of the owner. the chip is a little dusty in the photo but is in near perfect shape. anybody have any ideas as to its value? I picked it up at a sale of the old Pioche hospital located next to the current overland casino. Ive included a picture. any help would be apreciated.
