I am not sure if they used this mold or not,but I don't know.The thing is I've seen this with a Colbrandt's Flamingo Club,Reno on the other side,either the manufacturer was having fun with this chip with similar small circle molds or an error,I think having fun.Same picture on back as pg 211 in James Campiglia's book.So I still think Las Vegas or Reno of some sorts.I'll have to talk to James some day or maybe Roy Klein? This is a picture someone sent me and is a chip they have and this is front and back of one chip,so he says it's Colbrandt's Flamingo, and I guess the one side is,but does the SKY--- go along with this Club?Thanks for your response and if you find any more about it ,post it or send me an e-mail a mistery Id like to solve,Torrey
