I bought one recently and did a bit of research on it. After narrowing it down to a couple of locations, I contacted the seller. She bought it during a cruise which went to San Jose, Costa Rica in the late 1980's. I am glad to see that Michael Knapp supports my theory, since no one provided the Gaming Table information at the time. Actually, you wrote me at the time to ask if it was available.
For some reason, I really like that chip.
