i Just picked these up at auction. The seller got them from an estate sale and said they are over 20 years old. They have been keychain drilled from the 1 spot to the 3 spot. I was wondering if anybody has an idea if they are from Atlantic City. The seller said they were old table dice but they look like old giftshop dice. I do have some older table dice with recesed spots but they are nitrate. These apear to be acetate. I will have to put a hot needle into one of the drill holes to find out.
