My undstanding is that a very reputable member and former club president believes this to be a Vegas chip. The story I heard is that they were found in a batch of chips that included several Thunderbird chips that said Vegas on them. Now I cant say for sure whether the chips originated in Vegas and ended up in Ill, or the other way around. As Allen says, the logo does match exactly the logo of other Vegas chips, even if the mold does not. Remember that most chips from the Tbird in Ill feature a T mold and NOT the smkey. I think it is still very much an open issue.
