Æ20 - Caligula ΓΕΡΜΑΝΙΚΟΣ ΚΑΙΣΑΡ ΠΡΙΗΝΕΩΝ

Priene's civic coinage under Caligula is notably rare — the city was already in economic decline by the first century AD, its harbor long silted over and trade routes consolidated through Miletus. That Priene struck at all during this reign suggests a deliberate civic gesture, likely tied to the wave of loyalty emissions that swept the Greek east upon Caligula's accession in 37 AD, when cities across the Aegean scrambled to honor the new emperor through local bronze issues.
