Denaro - Bertram

Bertram of St. Geneviève held the patriarchate during one of its most turbulent stretches — his tenure ran through the Black Death's arrival in Friuli in 1348, a catastrophe that devastated the region's population and almost certainly disrupted mint operations at Aquileia. The patriarchate had long exercised temporal authority over a significant stretch of northeastern Italy, and its coinage functioned as genuine civil currency across that territory rather than merely ecclesiastical issue.

The fineness of .572 places this squarely within the gradual debasement trend visible across north Italian denari of the mid-Trecento.
