Hello,
The Franklin mint have 2 mintmark:
The famous FM:
But for France they were working behind the name of “Le Medaillier Franklin”
From 1976 to 2004 date when they file for bankruptcy.
In order to make the company a look a bit more french and as to import silver in France you had to put a weevil hallmark they start to engrave on the edge of their product design for france the mintmark: LM
So can we had this last mint mark to the Franklin mint?
All these information are comming from Polette on this thread (thanks a lot for the incredible job done).
