3 Cinquine - Filippo III

The cinquina was a deeply Neapolitan denomination, its name derived from the five-grain unit of account that had structured southern Italian commerce since the Aragonese period. Under Spanish rule, Naples functioned as a cash cow for the Crown — Philip III's wars in the Low Countries and along the northern Italian frontier demanded constant remittance, and the mint at Naples ran hard through the 1610s to meet it. The 3 cinquine sits at an odd fractional value that speaks to the practical demands of a market economy rather than any administrative tidiness.
