Hemichalkon - Artaxias I eagle

Artaxias I founded the independent Armenian kingdom around 190 BC after the Seleucid defeat at Magnesia left the region effectively ungoverned, declaring himself king with the tacit approval of Rome. His coinage is extraordinarily rare — the hemichalkon denomination, the smallest bronze fraction in his series, survives in only a handful of documented examples, and Kovacs catalogued it with minimal die information precisely because so few specimens existed to study.
