These are some older promo chips from Harveys in Lake Tahoe. TCR lists three colors, all of the same value (G). I finally got the red one from JerryO' this week and it's the first I've seen for sale. I would suggest it is scarcer.

These were released in the 90's and are TCR E8942, E1136, and N8559. A blue one sold at Saito's last auction for about $120 and Jerry's red sold for about $60. I'm not sure how to balance these against the number of NCV collectors out there, but I think some of the colors should be bumped up in Value. I was the winner on both these. I've had the lavender for quite a while and think it was priced pretty cheaply.

Does anyone know why there are three different colors? Maybe sold at different times?

Only the lavender is listed in The Chip Guide. These scans can be added there if anyone wants them.
