1 Ducat - Antonio Tolomeo Trivulzio Gallio

Retegno was among the smallest feudal lordships in the Lombard plain ever granted mint rights, and the Trivulzio Gallio family exercised that privilege only briefly — Antonio Tolomeo's tenure produced ducats across just a two-year window before the mint fell effectively dormant. The CNI records for this type are thin, with surviving specimens scattered across a handful of Italian institutional collections and almost never appearing in trade.

The fief itself passed through enough noble hands that establishing clean die attribution remains genuinely difficult. Fr#993 cross-references confirm the gold fineness held to the standard Milanese ducat specification.
