20 Nummi - Syracuse

Syracuse served as the Byzantine administrative capital of Sicily and, increasingly through the seventh century, a refuge mint as Arab expansion severed Constantinople's reach across the western Mediterranean. This issue falls within the reign of Constans II, who famously relocated his court to Syracuse around 663 — the only Byzantine emperor to govern from the west — though this coin predates his arrival by roughly a decade, struck during a period of acute fiscal pressure following the Arab conquest of Alexandria in 642, which destroyed a major source of imperial revenue.

The Syracuse mint was notoriously inconsistent in flan preparation and die alignment during this period, and weight variation across surviving specimens is substantial.
