Uncle Jim is a middle age man who travels the US buying up old, plain, clay poker chips. I sold him a 1 sq. ft. cardboard box full of plain clays about 5-6 years ago. He gave me the chip. He lives in Florida and I have his phone number. I have called several times to get his last name. I leave a message on his recorder but he never calls back. I will send his number and you can try to reach him.
