I found a box of 100 two square diamond poker checks, 99 chocolate in color and 1 yellow, 1-9/16", PETE hotstamped, made by S.F.Card Co., 100 Fillmore Street, San Francisco, Calif. Phone Market 1-9613, according to the label on the box. The brown chips are nearly perfect condition, but the yellow shows some use, and hotstamp fading. Sorry, scanner not working. I am looking for age and value. They are available for sale, as a lot.
