I got this from Duke Eyman the other day. It appears to the N4316 Luxor "Twin Q" chip, overstamped with a spiral cancel, then overstamped again with the Menominee Nation Casino logo. I believe these were picked up some time ago at the Menominee Casino in Keshena, WI.

Maybe they used them for tournaments, roulettes, or maybe just for gaming lessons, who knows?

What is the story behind the Twin Q chips though? Was it a game, a promotion or what?
