for most Caribbean countries for a long time (the Playboy chips are a possible exception). Of course, there is a fine guide for Puerto Rico by Archie Black, but not for most of the Caribbean. Therefore, the prices in those other guides are severely out of date, and should not be relied upon. The guides are still full of great information, though, and I would love to get one of the older Aruba-only guides put out by Ralph Pollack someday (though my hobby funds have dried up for the present time).
There are experts out there who might know the value of your chips. Unfortunately, I am not among them. Hopefully, one of them will chime in.
Good luck, Ruben.
