Since you seem to be collecting all coin center chips, have you ever seen this old website: "www.coincenterchips.com"? It has long been disabled, but you can check out the site on the wayback machine. I think it is only Nevada chips, though. Here is a link to all the sites archived. Some of the pics do not show up, but I thought it was a cool site with chip pics. Regards, Greg
