Tetradrachm HΞP, ∆C

Arados — the Phoenician island city-state that maintained striking autonomy long after most of the Levant had been absorbed into the Seleucid sphere — dated its coins by its own civic era, reckoned from 259/258 BC. The letters HΞP and ∆C are year and magistrate notations within that system, placing this piece precisely in the city's numismatic sequence even as Seleucid power was collapsing around it. By 92 BC, the dynasty was fracturing under rival claimants, and Arados had effectively been operating as a free city for decades, issuing silver on Phoenician weight standards largely undisturbed.
