I keep a file on the old gambling ships and so do some other collectors on this board. Only chips from the Tango and Rex exist to my knowledge. Some have been attributed to the Monte Carlo, but I don't think they have been verified. Would be more than happy to find out I am wrong, and that there are more chips out there to run down. I did find a Bingo Token from the Rex at an auction, but unfortunately it got away from me. John Long has a scan of it on his site
