I think that all the Lady Luck Triangle-Club mold NCV's may finally have appeared in the chip market. The beige ones were used years ago in their Win-Cards packets. I found the black, grey, and maroon (red) chips over the past couple of years. The green one was on eBay last week. All are available uncirculated so there were probably boxes of these sold after the LL closed. Given the colors, I'd say these were probably ordered as tournament chips, but since the green was never seen, it's likely they never used them that way.

Here is a picture of the 5 I know about. The green is not yet in TCR (12).

I wonder if the black TRICLB chip marked "Tournament Use Only, NCV" actually exists (V2876). I've never found one. There is one marked that way on the H&C mold though (N3545). Do you have a black TRICLB in your collection? Could be a TCR error.
