~~~ come out of Nice.

Not plastic but, rather a ceramic-type composition such as a CHIPCO.

Ten of these were found in a Paris shop 29 years ago and, I do not know of any others or any other denomination of the same series... and, one example is in the NICE book.

I am willing to trade this one example for either another denomination in the series or trade for a MOP plaque from Paris, Spa or Zoppot -- or a MOP catalog from Briotet/Caro or Jost and even artwork sheets and monogram sheets from any manufacturer of MOP.
