I'm talking about the bluish gray $1 chip (no inserts) with Caesar on a bed issued in the 1970's. It seems that there have been a lot of these on ebay lately. I also noticed many for sale at the convention in June. There was a find of about a box a few years ago. Has there been another find? Are the multiple chips now for sale from the original find? Has the number of known chips surviving increased? Any reply would be greatly appreciated. Thanks.
