Dupondius - Nero SECVRITAS AVGVSTI S C II, Securitas

Nero introduced the SECVRITAS AVGVSTI type shortly after the Pisonian conspiracy of 65 AD, a plot involving dozens of senators and equestrians that came closer to ending his reign than any external threat. The propaganda value was direct: security not of the Roman people, but of the emperor himself. That distinction was deliberate and, for Rome's senatorial class, uncomfortably pointed.

The Lugdunum and Rome mints both contributed to this series, with output expanding markedly after 65. Nero's broader bronze reform of 64 AD had already increased the weight standard for the dupondius, making these later Neronian bronzes physically heavier than their Claudian predecessors.
