Roman Imperial — Antoninianus
AD 255-256

Valerian I holds a tragic distinction in Roman history: he became the first Roman emperor ever captured in battle by a foreign enemy. The period AD 235-284, known as the 'Crisis of the Third Century,' saw Rome nearly collapse under civil wars, plague, and foreign invasions. Valerian led his army east to confront the Sasanian Persian Empire under King Shapur I. After his army was struck by plague, Valerian agreed to negotiate. It was a trap. The emperor was seized at Edessa in AD 260 and spent the rest of his life as a Persian prisoner. According to some ancient sources, Shapur used the captive emperor as a human footstool when mounting his horse. Persian rock reliefs at Naqsh-e Rostam still show Shapur triumphant with Valerian kneeling before him.

By Valerian's time, the antoninianus had become significantly debased — containing far less silver than earlier issues. Rampant inflation plagued the empire. The coin's face value was increasingly divorced from its metal content.

Role: Imperial capital
Despite the chaos of the third century, Rome remained the primary mint, though regional mints increased in importance as emperors needed to pay armies quickly.
