As - Tiberius Countermarked eagle left

Calagurris — modern Calahorra in La Rioja — was among the more prolific municipia striking bronze in the Tiberian period, its coins circulating widely through the Ebro valley. This particular piece carries a countermark of an eagle, a practice applied to existing coins to revalidate or reauthorize them for continued circulation, likely by local magistrates or military administrators. The eagle countermark on Tiberian provincials from Hispania is catalogued specifically as countermark 32 in the ACIP corpus, applied with enough frequency to suggest an organized, deliberate revalidation campaign rather than ad hoc field use.
