Question

How much would a sou, franc, louis, and pistol in 19th century France be worth today in American currency?

Answer 1

The French franc was the national currency of France from 1360 until 1641 and again from 1795 until 1999 (franc coins and notes were legal tender until 2002). Though abolished as a legal coin by Louis XIII in 1641 in favor of the gold louis and silver écu, the term franc continued to be used in common parlance for the livre tournois. The franc was also minted for many of the former French colonies, such as Morocco, Algieria, French West Africa, and others. Today, after independence, many of these countries continue to use the franc as their standard denomination.

The value of the French franc was locked to the euro at 1 euro = 6.55957 FRF on 1998-12-31, and after the introduction of the euro notes and coins, ceased to be legal tender after 2002-02-28 (although still exchangeable at banks).
