Follis - Constantius II FEL TEMP REPARATIO, Siscia

FEL TEMP REPARATIO — "Happy Times Are Returning" — was one of the more cynical slogans in Roman imperial coinage, issued across dozens of mints simultaneously from around 348 AD as the empire lurched through the civil war between Constantius II and the usurper Magnentius. Siscia, a strategically vital mint on the Sava River in present-day Croatia, was briefly held by Magnentius before Constantius retook it in 351 following the Battle of Mursa Major — one of the bloodiest engagements in Roman history, estimated to have killed over 50,000 soldiers combined.

RIC VIII 350 dates to the post-Mursa period, struck under Constantius's restored control of the mint.
