Issos sat at the northern tip of the Gulf of Alexandretta — the same narrow coastal plain where Alexander would later crush Darius III in 333 BC. The city's autonomous coinage was brief, confined to a tight window in the early fourth century before regional pressures ended independent issues. Few minting authorities in Cilicia produced silver at this weight standard for so short a period, which is precisely why the type appears across three major reference corpora yet remains genuinely scarce in commerce.
