I was very pleased to run across this NCV chip from the Desert Inn in Las Vegas at the Palace Station show. It's not listed in either Nevada reference. I'm assuming it was intended for promotional use in the Baccarat area as DI did have other $20 baccarat chips.

The holder was marked "2 known"; anybody out there have one of these? I'd put it in the O to Q value range; maybe higher for the right buyer but I don't go much above that range for NCV's.
