Æ20

Pergamon passed to Rome in 133 BC when Attalus III died without an heir and bequeathed his kingdom outright — an act his subjects found sufficiently outrageous that a pretender named Aristonicus spent the next four years fighting a war to reverse it. Bronze civic coinage continued through and after that conflict, produced now under Roman provincial oversight rather than Attalid royal authority, a bureaucratic shift that left little visible trace on the coins themselves.

SNG von Aulock 1380 places this piece within a long municipal sequence that ran well into the Augustan period.
