The different colors of the FQ's tokens came out of different machines. Video Poker, 25¢ slots. $1 slots, etc. They dropped out of the machines with so much coin in. You could take them to the Reel Winners booth and trade for merchandice, comps, or cash. It was an early attempt at a slot club and the FQ's had a patent on it. They also used it at the Atlantis in AC. The Rio paid for the rights to it, and used it for awhile after they opened.

I have dark purple, light purple, silver, and gold. I need the green one if you have a trader.
