In 1721, Bologna existed within a complex monetary landscape typical of the Italian peninsula prior to unification. The city was part of the Papal States, meaning its official currency was the Papal
scudo, along with its subdivisions like the
giulio and
baiocco. However, the practical reality was one of significant monetary pluralism. A multitude of foreign coins, particularly Spanish silver
reales and gold
doppie from various Italian and European states, circulated freely alongside papal issues, their value determined by fluctuating market agreement rather than fixed decree.
This system created chronic instability for commerce and daily life. The intrinsic value of a coin (its metal content) was paramount, leading to frequent clipping, counterfeiting, and the hoarding of "good" heavy coins, which left worn or debased coins in common circulation. Furthermore, the exchange rates between gold, silver, and copper coinages shifted constantly, often manipulated by money-changers (
banchieri). For Bolognese merchants and citizens, this meant prices and contracts often had to be specified in a particular named coin, and routine transactions required careful scrutiny of metal weight and fineness.
The situation was a source of frustration for both the municipal government and the papal legate who ruled the city. While the papal authorities in Rome periodically issued edicts to fix exchange rates and prohibit certain foreign coins, these attempts at control were largely ineffective against entrenched market forces and regional trade necessities. Consequently, Bologna in 1721 operated with a fragile and often chaotic monetary system, where the official currency existed alongside a shadowy but essential economy of valuation and exchange, reflecting the city’s position at the crossroads of regional and international trade.
