Can anyone tell me the approximate value of the $500 Palm Hotel & Casino chip (Puerto Rico) and the $500 Chipco sample chip (has Chipco contact info on reverse) in the scan below? They are both oversized. The Bay 101 chip, a standard sized chip, is included to show size. The chipco chip is slightly larger. They are for sale or trade, by the way, if anyone is interested in either or both.
