I cannot find the illustrated list that was posted here showing chips that were used in Cuba... and the Briotet (CARO) paper only shows a bicololor 100 in "CASINOS" and not much more that I can find.
I still have no idea why the red fiill on the 20 and if my 100 was also known in Cuba.

I am interested in J-C's 500.
