French sol
From Infogalactic: the planetary knowledge core

1791 30 Sols depicting Louis XVI.
The sol was a coin in use in Ancien Régime France, valued at a 20th of a livre tournois. The sol itself was subdivided into 12 deniers.
Over the 17th century the term sol was, apart from in a few instances, progressively replaced by sou, reflecting its pronunciation. In 1787 a sol's buying power was roughly equivalent to that of a Euro from 2005.[citation needed]
