Last year after never finding information on different Casino .999 silver denominational tokens I decided to do a bunch more work and wrote a book on just this. There are just under 500 different listings in here. And from any casino any where around the world. Mostly though from the silver state of Nevada. I can send you a nice new copy for $40.00 plus $3.99 Media rate shipping. You are welcome to post here or PM me. Thanks for reading.
