Aureus of Claudius, struck at the Lugdunum (Lyon) mint, dated 41–42. The depiction on the reverse meant to commemorate the "reception of the emperor" (imperator receptus) at the Praetorian Camp and the protection the Praetorian Guard afforded Claudius in the days following the assassination of Caligula. Issued over a number of years in both gold and silver, these type of coins were struck to serve as part of the annual military payments Claudius had promised the Guard in return for their role in raising him to the throne
Claudius issued this denarius type to emphasize his clemency after Caligula's assassination. The depiction of the goddess Pax-Nemesis, representing subdued vengeance, would be used on the coins of many later emperors.
