The two bottom chips are frequently referred to as the "Redfield Chips" because they were reserved for use by Lavere Redfield - a notorious high roller at the roulette tables. Dwayne Kling's book mentions that Colbrandt's Flamingo Club allowed him to play $100 straight up on the roulette tables - a pretty sizable bet in the 1940's. The story goes that these chips were only used by Mr. Redfield and the denominations were set at the time he played. Redfield was one of the largest land owners in the Reno area but a bit on the eccentric side. The story I heard was that he would walk into town from out near the Mt. Rose highway to bid on foreclosures on the courthouse steps. He would then go on into town and play roulette at the Nevada Club. He had a car but wasn't willing to pay to repair it so he could drive into town. There is a Redfield Plaza shopping center just across South Virginia St out near the Convention Center that I think is named after the family. Not sure how much of that it accurate but I think the story on the chips is pretty well documented.
