Other than the Chandris line of chips listed on ChipGuide, these items along with the run-of-the-mill array of ashtrays and barware, I find nothing else showing any specialized chips with documentation other than Tom's original mention in his book and other mentioned info that Playboy certainly had an operation going on aboard the Atlantis and, I would only guess that maybe London Playboy chips, as Torrey mentioned here, were used on the Atlantis which, ChipGjide shows us London casino chips used at sea with overstamped $ denominations and other metallics mentioning a UK property or operator at sea with a ship name. I am only sorry that I never asked the question way back during all my phone conversations with those at Playboy headquarters In Chicago back when I first introduced the BJ training school chips to the hobby that I bought from an executive (archived here)... Other than those whom I bought directly from who worked in Nassau, Manchester and Portsmouth. there is only Barry, Tony and Rita who opened house here in Freepprt and Mr Hamilton left to ask if they know who worked on the Atlantis back then and,,even then, hardly anyone recalls anything about chips, especially what graphics were depicted...
