Dupondius - Nero SECVRITAS AVGVSTI S C II, Securitas

Nero introduced the SECVRITAS AVGVSTI type in the early 60s AD as a direct response to the Pisonian conspiracy of 65, broadcasting imperial security — his own, specifically — to a population well aware of the assassination plots circulating in Rome's upper classes. The orichalcum dupondius, revived and standardized under the Neronian coinage reform of 64 AD, gave these political messages unusual visual currency through their distinctive brassy color, which set them apart from the silver and bronze denominations at a glance.

RIC I 194 falls within the later phase of Nero's reformed coinage, after the mint adjusted both weight standards and module following that 64 reform.
