Here are the only chips I have ever seen from Casino Cancun.
They are in glass. Made by Paulson in 1998. I found the plaque in a junk pile being readied to go out to the garbage, when Paul-Son was closing down their retail store.

Casino Cancun was to be operated out of Cancun Mexico. The Mexicans said no. The 3 pictures below was taken in Haifa, Isreal, where the boat wound up. Not sure when they were taken. I have an earlier picture of the boat sitting in Haifa, the boat is in disaray, looks neglected. Can't find it.
