As - Augustus and Numa Pompilius CN PISO CN F IIIVIR A A A F F

Cn. Piso served as one of three moneyers (tresviri aetere argento auro flando feriundo) appointed around 16–15 BC, a period when Augustus was reorganizing the Roman monetary system following the settlement of 23 BC. The pairing of Augustus with Numa Pompilius — Rome's legendary second king and credited founder of its religious institutions — was a deliberate political alignment, presenting Augustus as a restorer of ancient Roman piety rather than a monarch in the Greek sense.

The Piso family connection is worth noting: Cn. Calpurnius Piso, likely a relative, would later become notorious as the man accused of poisoning Germanicus in 19 AD.
