1 sesino - Guglielmo I Malaspina

Guglielmo I ruled Tresana as one of the smaller Malaspina partition territories — the result of centuries of inheritance divisions that had fragmented the original marquisate into a patchwork of micro-lordships across the Lunigiana. By the mid-sixteenth century, several of these tiny signorie retained the nominal right to strike coin, though output was limited and the pieces circulated largely within purely local exchange. The sesino was the most marginal denomination in the billon hierarchy, and surviving examples from Tresana are scarce enough that the CNI type series relies on a handful of specimens.
