It appears that they are the only French casino, or maybe just one of a very few; that had such a large array of so many intertwined and back-to-back CC monogrammed
chips, jetons and plaques with some being only a minute variation while others being a completely different configuration of the CC.

We do know for a fact that there were a few French casinos where some of their CC Mother-of-Pearl monogrammed chips were transferred to one or two other casinos in France, some even being quite close in design while being used on certain games... and, in one or two known cases it was inventory returned to.the manufacturer and then resold. We have seen pen and ink documentation backed with actual packaging.
