Table games BJ ect. using these chips are illegal in Mexico, but authorities take bribes from two casinos in Mexico (that I'm awar of) Playboy in Cancun, and Caliente casino in Tijuana. These casinos are very profitable, and can afford to pay the bribes. These games will remain if profitable enough) So these chips are actualy, ILLEGAL CHIPS, and these tables could close at any time. The Playboy did close tables a while back but recently re-opened, different chips. Dr. Luis Alvarez is very qualfied about gaming in Mexico, he speaks spanish, has given medical classes in Tijuana, and other cities,and studied gaming for years. I have a few chips left e-mail me if interested. Will put on e-bay in a couple days.
