Hi Carlos. I don't know about other collectors, but I'm a spreadsheet nerd and have catalogued all of my chips, including the CG number (and TCR numbers for Nevada chips). I do have some African chips, but it would be difficult for me to try and identify them by picture alone. What would help me (and others, perhaps) would be if you posted a list of the CG#s. With that, I can use the vlookup command in excel to quickly identify if I have a chip you're looking for or not.

If anyone reading this would like to know how that's done, along with other excel tricks, maybe I can set up an educational zoom call or present something at the convention (if we have one this year, haha).

Anyway, good post and good luck!
