I have recently purchase a $1 chip from the Allan Boyd Club. This chip has been attributed to Reno, NV. and is listed in the 3rd Edition of the Official U.S. Casino Chip Price Guide. The seller also has a 50c chip that looks exactly like this chip except it has a 50c instead of $1, green and a different mold (see scan below). This chips is not listed in the price guide.

Can any Reno expert give me some insight into this chip and the casino and what its approximate value might be?

Thanks in advance for any help or knowledge you might be willing to share.
