Some Paris antique shops feature window displays of vintage chips, though they are mostly Vichy and Med in bulk.

There was a nice Mother-of-Pearl Paris find recently from Cercle de la Presse. Chips and plaques we never knew existed; well over 100-years old and not on ChipGuide, either. They now rest in a California.antique shop and easy to find on line... If this is not a successful Paris chip find, I do not know what is... plaques that some of us would have paid dearly for... 😀

Check around for other denominations from here.😀

Good luck...!!!!
