Yes, it was the house chip and an early Reno Air Races in 1993. Also, the only chip to celebrate the Air Races and Balloon Races on the other side...the same year. The only chip so far to celebrate both. I have them for sale in new condition, for $12. Also, the last rack chip was the $1 mustard, a $5 orange chip that was replaced by the $5 chipco mentioned and the $25 chocolate that was never "no cash valued" as the other Large greek keys. the $100 was the only other chip without the NCV. I have all of these to trade or selll if anyone is interested. The maroon $2.50 was sent to be cancelled as the others, but never returned to the casino before they closed and the outfit that was responsible never revealed their final destination. Jerry Wall bought the rest.
