1 Tremissis - Aripert I

Aripert I came to power after the death of Rothari, whose long reign had seen the Lombards consolidate control over much of the Italian peninsula. The tremissis — one-third of a solidus — was the workhorse denomination of early medieval gold coinage, effectively inherited from late Roman and Byzantine monetary practice. Lombard rulers struck in imitation of Byzantine types precisely because Byzantine gold retained international credibility that no upstart Germanic kingdom's coinage could yet command on its own.

Aripert's reign ended with his death in 661, after which the kingdom split between his two sons, triggering a civil war that would reshape Lombard Italy within a generation.
