Ambrosino - Luchino and John Visconti

Issued jointly under Luchino and Giovanni Visconti, who ruled Milan together following the death of Azzone Visconti in 1339, this gold ambrosino belongs to one of the more politically awkward co-lordships of 14th-century Lombardy. Luchino held military and administrative control while Giovanni, as Archbishop of Milan, provided ecclesiastical legitimacy — an arrangement that worked largely because neither fully trusted the other. Luchino died in 1349, almost certainly poisoned, with his wife Isabella among the suspected conspirators.

The ambrosino denomination itself traces to earlier Milanese communal coinage, consciously revived by the Visconti to anchor their authority in the city's pre-imperial monetary tradition.
