This has been in my collection for years with no attribution. I went through the New Campiglia Wells book to update my $100 collection and found that James had a good idea of the location. Turns out it is Las Vegas. Not for sale, just for show. By the way, I highly recommended updating your old 3rd edition book with the new 4th edition of The Official US Casino Chip Price Guide. James and Company did a great job updating the book and I pulled a lot of new information from it. Indispensable for me!
