I am new to the hobby and picked up a Commemorative Chip Set from Resorts International in Atlantic City for their 20 year anniversary 1978 - 1997. It is in a black hard cover box that looks like a book, with nice gold lettering. On the inside are 20 different chips depicting an event from each of the 20 years being celebrated. Does anyone have an idea of the value and mintage? Please email for a picture.. I will try to add a picture to the site (but My AOL members service is not letting me add one at this time.
