I recently acquired a red $5 Mapes-Reno chip. Hourglass mold, 312 edgespots in black, green and yellow. (Sorry, haven't scanned it yet, but I can if need be.)

I don't see it listed on silver state treasures (which I consider an authority on Nevada chips).

So what do I have? Is there a TCR # for it?
