10 Zecchini - Antonio Teodoro Trivulzio

Retegno was a tiny fiefdom in the Duchy of Milan granted to the Trivulzio family, who held the right to strike coinage — a privilege that, by the late seventeenth century, was increasingly anomalous and jealously maintained. Antonio Teodoro Trivulzio used that right aggressively, producing oversized multiple-zecchini pieces that served more as demonstrations of jurisdictional authority than as practical trade instruments.

The 10 zecchini format at this fineness placed it among the heaviest gold issues from any Lombard feudal mint. Surviving examples are rare; Retegno's total monetary output across all denominations was negligible against the broader Milanese economy.
