Historical context

Kalchedon, also known as Chalcedon, was an ancient maritime town in Bithynia, Asia Minor, situated on a small peninsula along the north coast of the Sea of Marmara near the mouth of the Bosporus strait. Greek colonists from Megara in Attica founded the settlement in 685 BC, placing it almost directly opposite Byzantium across the strait. During the Classical Period, the city operated as an issuing authority, producing civic coinage such as this silver drachm struck to the Persian weight standard between 387/6 and 340 BC.
