Florentine Economy
by Sevrin de Savage [Aaron D. McClelland]

Monetary System of Florence
Florence, in the 13th through the 15th century employed two parallel monetary systems; The Gold system which was based on the Florin and the Silver system based on the Lire. Depending on the availability of coinage in circulation, pepper and saffron were also used as a trading commodity. The actual availability of coinage could be affected by harvests, fairs, ship sailings, and large expenditures by nobles and businessmen.

The Gold System
When the Florin was first issued in 1252, it weighed 72 grains and was 24 carats fine. On one side it bore a likeness of Saint John the Baptist and the Lily of Florence on the other. It became the standard gold coin used in Europe. Through the years the weight of the Florin was often debased by foreign mints, forcing Florence to issue new coins periodically with higher weights and content.

In 1450, a new Florin was issued to reestablish the Florin as the standard of gold coin in Europe.

One Florin
=
20 Soldi a Oro
=
240 Denari a Oro

In Florence the Florin Gold standard was used for large contracts and trade. Wages and common daily expenses where paid using the silver system. To maintain the strength of the Florin and to prevent ‘shaving’, the Florentine mint would issue specially sealed small leather bags with specific numbers of Florins within. Very high penalties were assessed on anyone altering the sealed bags or contents.

The Silver System
The silver system in Florence was based on the Lire. Though the value of the silver Lire would depend on the European value of the gold Florin, in 1480 one Florin was approximately worth four silver Lire, or 80 silver Soldi.
