Nummus - Constantius II FEL TEMP REPARATIO, Siscia

The FEL TEMP REPARATIO ("happy times are returning") coinage was one of the most ambitious mass-issue campaigns in late Roman monetary history, launched under Constantius II and his co-emperors to celebrate the 1,100th anniversary of Rome's founding. Siscia — modern Sisak in Croatia — was among the most productive western mints of the period, and its output of this type was enormous. The specific falling horseman reverse on these smaller bronzes became so ubiquitous across the empire that forgers produced contemporary imitations in staggering quantities, many of which are now nearly indistinguishable from official strikes.

RIC VIII 243 places this piece in the period just before Magnentius's usurpation in January 350 effectively ended Siscia's production under Constantius's authority.
