Hi Karen,
Welcome to the hobby!
I have "The Chip Rack: A price guide to Casino CHips and Checks of Nevada", but this is a rather in depth and pricey book.
I personally like The Official US Casino Chip Price Guide, by Campiglia and Wells better...it is easy to carry with you and has color pictures. The price is right too! When I was a new collector, this book helped me alot!
Please don't forget to check the club's website at www.ccgtcc.com
Good Luck and have fun!
