1 Grosso `Ambrosino` - First Republic Gothic M

The "Ambrosino" takes its name from Sant'Ambrogio, Milan's patron saint, and was introduced during the city's first experiment with republican self-governance following the expulsion of the Visconti in 1302 — though the type itself began striking somewhat earlier, under the communal government that preceded full Visconti consolidation. Milan's mint was among the most productive in northern Italy during this period, feeding a commercial economy increasingly dependent on silver for long-distance trade with transalpine merchants.

The Gothic M variety of MIR 67 is distinguished by its letterform and places it within a tight chronological window of communal issue before dynastic coinage reasserted itself.
