Denarius - Augustus VOT P SVSC PRO SAL ET RED I O M SACR, Mars

This denarius belongs to the monetary reforms Augustus pushed through following his return from the eastern provinces in 19 BC, a period in which the senate voted extraordinary public vows — the VOT SVSC PRO SAL ET RED — for his health and safe return. The vows were formally discharged in 18–17 BC, and the coinage commemorating them was almost certainly struck under the supervision of moneyers acting within Augustus's newly tightened control over the silver and gold supplies, wrested from senatorial oversight around 15 BC.

RIC I 150A is among the scarcer variants within this vow series.
