I have a few sets of these old DIASQR (diamond square) monogram chips or . Nice thin S hot-stamp. Made by the Pioneer Club Supply Co. of San Francisco. It may be hard to see, but the colors are: white, red, blue, & yellow. Used, but nice condition.

I'll trade for older clay molded chips with a single letter monogram. Or, I'll sell a set of 4 chips for $5 delivered to an address in the USA. If a collector outside the USA wants a set it's $3.50 & you pay the postage.
