I was the winner of eBay auction #371189461595. It's a red Ewing mold chip with the block letters "JC" on each side. I wonder if it's from the Jackpot Casino on the Vegas strip back in the 1970's. I really have no idea except that eight of the ten Jackpot chips in TCR are Ewing mold (maybe 8 of 9 as I've never seen an N0940) and several of the chips are only marked with the letters "JC" in both cursive and block letters. If it's not a Vegas chip then I'm out $0.54. Sometimes you just got to gamble.
