Sol Publique Deposited
The word is derived from Solidus and was later corrupted into Sou. It did not long retain its original name of Sol d'Argent, as it was struck in copper during the sixteenth century, and during the first French Revolution pieces of one and two Sols appeared in bronze, a metal obtained from melted bells.
Of other multiples there are pieces of one, six, and twelve Sols in copper for Geneva, struck in 1590, for the pay of soldiers ; billon three and six Sols were issued in Luxemburg in 1790; one, two, and five Sols were used during the siege of Mainz in 1793; there are also issues for the French colonies. The Sol was part of the following system:
During the first Revolution the Sol was divided into five Centimes, and the two Sou piece was called a Decime. The name Sou is still used in France for the five Centime piece.
