Until recently only two crest & seals were known from the Casino de Puerto Rico - a red and yellow from 1923.

Who knew that the 5 colors of CPR shown in the USPC salesman sample book would become available. Therefore there are now 7 chips known, 2 reds, 2 yellows and a single white, blue and green.

At this point a collector has the yellow, another has the red and I have the 5 shown below. To my knowledge, no chips are held by the big collectors that reside in Puerto Rico.

Although 5 colors were shown in the records, I am not convinced there aren't other colors.
