Hey Greg and Gene!

The chips in question were used at Crystal Park in Crystal City (Compton) CA.
As I understand it, the main reason the chips were removed and replaced was due to the problems stacking them. They're too slippery, and would not stay in a stack. I was able to pick up a few of the canceled chips at the Paulson Store last November, and don't recall if they were still available last June...

One way to see if you have one of these chips is to look at a stack on chips, and if you see a clear spacer between two chips (looking at the edge) then more than likely it is one of these chips...
