Any of the Playboy Hat & Cane issues sell for $25 to $50. These are the oldest issues dating back to May 1966 and I am convinced, were never used in the casino, which is why you always see them in new condition. These were ordered and not used due to a business dispute. Instead the small crown series was used in London from June 1966 to 1971. The H & C chips did show up at the London casino once and were traced back to a Las Vegas executive at that time. Apparently quite a number survived. Tom
