France had 5 republics. You probably have the 5th Republic - post World War 2. These coins were officially replaced by the Euro around 1999 - 2001. 10 F are worth 1. 5 Euro or about @2. 25 us. Unfortunately, most exchanges do not buy coins - too heavy to ship. A bank in France might convert them into Euro.
