Here is the front and back for the hilton chip I found with the California Club chips. I have been told that it is a roulette chip but there has not been an exact ID of the chip. I guess one side of the chip is supposed to have an A or B on it and as you can see no A or B. Any info would be great and I do have some of these to sell or trade. I collect HArd Rock or Halloween Chips. Thanks!
