Dupondius - Vespasian PAX AVGVSTA S C, Pax

Vespasian struck this issue during the consolidation following the Year of the Four Emperors and the destruction of the Second Temple in Jerusalem — the Pax Augusta reverse was a deliberate political message, not a decorative choice. The civil war of 69 AD had left the Roman treasury gutted and the mint system in disarray; Vespasian's early bronze coinage was partly an exercise in restoring public confidence in the currency itself.

The S C authorization mark on bronze and orichalcum issues had, by this point, become largely ceremonial — Senate control over base metal coinage was nominal under Flavian rule.
