Here is an obsolete $20 roulette jeton from the MGM Grand in Las Vegas that was new to me when I got it on eBay last month. The plain red jeton is listed in TCR, but not this one with stripes. I consider it an N-value chip.

Anyone know if there was a 20 with the half-round edge spots as on the $10 jetons?

These chips were used in the French Roulette game that was removed from MGM Grand about 5 years ago, only to surface recently at Paris in Las Vegas... and then disappear again.
