This section will be right up GDJMSP & Ian's streets,as they are very interested in collecting French coins.This is about the privy marks on French coins,which are usually found flanking the date on modern coins, including the Euro coins from France. Aidan.
All privy marks and mint marks of France are beeing detailed in Krause catalog at the beginning of the France coins section. I have the old 1995 volume which explaines them through the years 1801 - 1995.
