Needless to say, you have a fabulous collection there. Back in about 2013 a few collectors and myself were working on a photo project trying to get as many photos of of actual chips that were in Dale Seymour's book. It was great fun and scans of chips came from many people. I noticed one of the White's chips you showed is the same chip in our photo project. I really have no idea who sent in that chip scan. It just shows how chips move around in our hobby. It was really great to see so many samples.. Have you ever looked at the Gambling Manufacturer section in Dale's book? Check out the "Other Guides" on the Chip Guide home page and click on Gambling.
