... left out of half a box I bought a couple of years ago. Didn't record the numbers I've traded, sold or given away, but the ones I have left fall into the following ranges:

A131 thru A806
B182 thru B986
C004 thru C907
R182 thru R777

Also have one $1 chip with serial number Q588.

Hope that helps ----- jim o\-S
