Didrachm

Pergamon's silver didrachm belongs to the civic coinage the city struck after Rome dissolved the Attalid kingdom in 133 BC and reorganized the region as the province of Asia. The transition from royal to autonomous civic coinage was administratively abrupt — Attalos III's bequest of the kingdom to Rome left Pergamon's minting apparatus intact but stripped of royal authority almost overnight. The city nonetheless retained considerable prestige and continued producing quality silver under its own name.

The date range straddles both the late Attalid period and the early Roman provincial era, making attribution of individual specimens to one political moment or the other genuinely difficult without die study.
