As - Vespasian SECVRITAS AVGVSTI S C, Securitas

Vespasian struck this issue in 71 AD, the year following his formal recognition as emperor after the brutal civil war of 69 — the Year of the Four Emperors — which had seen Galba, Otho, and Vitellius all rise and fall in rapid succession. The SECVRITAS legend was a deliberate political message: Vespasian needed to project stability to a Roman populace that had watched three emperors die violently in under eighteen months. The Flavian dynasty was new, its legitimacy built on military force rather than Julio-Claudian blood.
