I like the designs on French coins, and this one is no exception. I am not sure if that is Miss Liberty, the French emblem Marianne, or just one of those pretty French women. The same pattern, however, has been used on-and-off for more than a century.

Here is a run-down of approximate catalog values for the various coins which use this pattern. For silver coins, they cannot be worth less than their weight in silver. Use kitco.com to find the current value of silver per troy ounce.

50 CENTIMES 1897 TO 1911 (0.067 troy ounces silver)

fully uncirculated: $30
coins dated 1897, 1903, 1905, and 1911 are more rare, worth about four times these values

50 CENTIMES 1912 TO 1920 (0.067 troy ounces silver)
