In 1675, Milan, as the capital of the Spanish Duchy of Milan, operated within a complex and strained monetary system characteristic of early modern Europe. The currency in circulation was not a single, unified coinage but a mosaic of domestic and foreign coins. The primary unit of account was the
lira imperiale (imperial lira), divided into 20
soldi or 240
denari. However, actual physical coins included local silver
scudi and
lire, alongside a flood of foreign silver from neighbouring states like Savoy, Venice, and Genoa, as well as Spanish
reales and gold
doppie. This proliferation created chronic confusion in exchange rates and facilitated clipping and counterfeiting, undermining trust in everyday transactions.
The situation was exacerbated by the fiscal demands of the Spanish Crown, which was frequently at war. Madrid often ordered the debasement of coinage or the minting of low-quality
moneta nera (black money, or billon coinage) to extract seigniorage revenue to fund its military campaigns in the Netherlands and elsewhere. This practice, while providing short-term cash, triggered Gresham’s Law (“bad money drives out good”), as merchants and citizens hoarded older, higher-silver coins. The result was a chronic shortage of sound money for commerce, price inflation for goods priced in the debased currency, and a disconnect between the official accounting lira and its actual metallic value.
Consequently, Milanese merchants, bankers, and the public had to navigate a dual challenge: a volatile bimetallic ratio between gold and silver coins, and the fluctuating values of countless coin types. This environment necessitated the expertise of money-changers (
banchi di cambio) and led to the increasing use of credit instruments like bills of exchange to conduct larger transactions without handling physical specie. Thus, in 1675, Milan’s currency situation was one of underlying instability, marked by a struggle between the disruptive fiscal policies of a distant sovereign and the pragmatic needs of a major European financial and commercial centre.
