Very interesting, you really did some research. Good job. Whenever I tried to google it I only found links that were written in Spanish, which unfortunately I cannot read. I wonder if he possibly even had the chips custom made for use in his home, for personal games and stuff... seems like the kind of guy who might do something like that. The guy I bought all the chips from about 9 years ago, I wish I had thought to ask him all this stuff at the time. Thanks for the info. And it's cool how you cropped my chips and made them look much better. At first I was wondering where you found those images until I realized they were mine. I've decided to gift the Castillo Piria set to my boyfriend. It's a nice set and now I can tell him the history of it.
