As - Agrippa S C, Neptune

Agrippa died in 12 BC, yet this as was struck under Caligula some four to five decades later as a posthumous tribute to Augustus's greatest general and son-in-law. The issue was almost certainly politically motivated — Caligula's father Germanicus was Agrippa's grandson, and honoring Agrippa reinforced the family's Augustan legitimacy at the start of a new reign.

RIC I 58 is one of the more frequently encountered aes issues of the Julio-Claudian period, suggesting it was produced in substantial numbers. The SC on the reverse confirms senatorial authorization for the bronze coinage, a formality that remained intact throughout the early imperial period.
