~~~ chips.

The CC mother-of-pearl was unknown prior to me finding it and, it clearly says the city name of ROYAT. (continue scrolling down)

On the reverse and under the denomination is another monogram; CI. (continue growing down)

Prior to the find I noticed a CC plastic (Celluloid) chip without any casino name on the obverse with the same configuration as the MOP. (continue scrolling down)

...and, on the reverse and below the denomination is the same CI second monogram as on the MOP.(continue scrolling down)

Nobody who collects France for over 55-years knows what the CI monogram is... nor do they know why it is on a chip that already has a monogram... (You can stop scrolling down now)

Any ideas, please?
