4 soldi - Siro d'Autriche prince de Correggio

Siro d'Austria inherited Correggio through a line so entangled with the Habsburgs that his very surname reflects the politics of legitimation rather than blood. The principality itself was a relic — a pocket lordship in the Emilian plain that survived into the seventeenth century largely because no larger power found it worth the diplomatic trouble of absorption. Billon coinage of this quality and weight was the workhorse of local small trade, minted in quantities calibrated to a circulation radius that rarely extended beyond the market towns within a day's ride.

The MIR 192 reference covers multiple die variants across IX#129–134, suggesting continuous production rather than a single emission.
