Per "The Official US Casino Chip Price Guide" Campigia/Wells there are only 12 known to exist...This chip was put on a 25¢ dice table only two days before the casino unexpectedly closed. This chip was mixed in with the inlaid 25¢ chips that were becoming short supply. Valued at $100-$150-$200. Front and back side shown. Selling for $50.00 to the 1st e-mail received. Thanks
