8 soldi - Siro d'Autriche prince de Correggio

Siro d'Austria was the last ruling prince of Correggio, a tiny Imperial fief in Emilia whose independence survived largely through the family's careful cultivation of Habsburg patronage — the "d'Austria" suffix itself adopted to signal that alignment. The principality was absorbed into the Este Duchy of Modena in 1635, making this billon issue one of the final coinages struck under Correggio's independent authority. The CNI records at least nine die variants for this type across the reference range, suggesting sustained production across the full span of Siro's reign rather than a single mint episode.
