~~~ I've been told about?

I understand it's mostly casino employees (like Gaming Floor) but who have been trading chips for many years.

I've been searching in French but find nothing except France eBay links.

I have a couple of these vintage 50.000/500NF plaques from the 50's that were revalued in 1961 to conform to the French Monetary Reform Act where every 100 French francs became 1 New franc (NF).

They're $50 each.

I also have two of the rectangle 10.000/100NF plaques for $40 each... and maybe one or two of the oval 5.000/50NF plaques also for $40.
