Countermarks such as "AVC" and "IMP" are relatively unspecific and were likely used since ca. 15 BC well into the Tiberian period. They occur from Gallia to the lower Rhine to the lower Danube region. Shapes and sizes vary however and allow sometimes a more specific attribution.
The AVC countermark is attibuted to Augustus. It occurs mostly on Lugdunum AEs, but some also on Nemausus AEs, or on Moneyer AEs.
The reverse of this coin features the celebrated Altar of Lugdunum which had been dedicated by Augustus on August 1st, 10 BC.
Am 1. August jeden Jahres feierten die 60 civitates der drei Gallien an diesem Altar ein Fest, mit dem sie ihre Reichstreue bestätigten. Der Altar war im Jahre 12 v. Chr. von Drusus errichtet worden.
