"The Official U.S. Casino Chip Price Guide" is the name of a book written by James Campiglia and Steve Wells. It has a ton of pictures and information that I find very helpful.

As far as I know, the only publication that is officially sanctioned by the CC>CC is the quarterly magazine that is published by the club.

Didn't want to mislead anyone into thinking that the C&W guide has the status of being the official guide of the hobby!
