Allan,
The Roulette chips shown in the bottom row of the scan are the style I beleive you have listed in TCR. I checked Howdy's auction #28 and Lot 353 is a light green Palace Station "B" EXACTLY THE SAME AS THE ONE IN MY SCAN, 2nd row on the left. I have known about this style of Roulette chip from Palace Station since 1993. I purchased my light green "B" from Jimmy Campiglia on December 23, 1993. I still believe the Yellow Roulette in the top row of the scan is an Unknown Style. They don't call me "Mr. Roulette" for nothing. If any one has seen this style of roulette chip or has another one from this Series, please LMK.
Till later,
Jerry
