The last time I went to the Long Beach show was around 25 years ago, so anything is possible.
But ... at that time, there were 3 chip dealers out of 200+ total dealers (coins, etc.) and 2 of those 3 dealers were C.T.Coin (Charlie Rogers, now passed away), and Henry Garrett (also, now passed away). I don't recall who the 3rd one was.

If you go, I'd like to hear if there were chip dealers there. Good luck if you go; hoping for the best, but I'm not going to invest time/expense to go. JMHO.
