This paper chip in a thin plastic holder was also sold at Doug's auction. I realized afterwards that I already had the one from owner W. Martello. It sold in the auction for $70 plus commission. It is $150 in TCR (N6178). These date to the 50's or 60's. Same size as a casino chip.

This one is not quite flat, as is often the case with the flexible plastic covered paper. If anyone needs it, you can have it for $75 delivered.
