Luke - you had listed an error picture of the DB chip with CB on the other side. I do not have that type of chip but I have separate CB and DB chips. Each say Dorado Puerto Rico on the chip. If CB is Cerromar Beach was that a separate location from DB (Dorado Beach??). Here is a scan of the chips that I have, each type in different colors.

Thanks for any info you can provide.

Ciao,
