Among the more collectible and valuable coins from France are the 50-franc coins produced in the 1860s These coins can be identified because they contain an image of Napolean crowned with a laurel wreath around his head.
The oldest French coins date back more than 2500 years, to the time in which Greeks and Celtic Gauls colonized the area. Coin production has continued in France unbroken since that time, and some rarities include ancient Roman coins, medieval French coinage, and coins from the French Renaissance.
Because of their historical importance, some of the most collectible French coins come from the time of the French Revolution, which occurred from 1789 to 1798. Some early coins still contained the image of the French monarch, but replaced the king's coat of arms with the image of the Spirit of France. After the execution of King Louis XVI, new coins were produced, among which were coins that held the image of Lady Liberty.
Further changes saw coins that represented the new French monarchy and, later, the image of Louis-Napoleon Bonaparte after his coup in 1852. French coinage continued to change, reflecting historical events such as World War II, up until the adoption of the euro in 2002.
