1/4 Tercenario

Issued under William II of Sicily, whose reign marked the political apex of the Norman kingdom before the Hauteville line collapsed into the chaos of succession disputes and eventual Hohenstaufen annexation. The billon tercenario and its fractions circulated in a monetary environment that was genuinely trilingual — Arabic, Greek, and Latin all appeared on Sicilian coinage of this period, reflecting an administration that had absorbed Fatimid fiscal structures wholesale rather than replacing them.

The fractional denomination suggests small-transaction demand in a densely commercialized Mediterranean port economy.
