Chalkon - Ptolemaios Tetrarch

Seleucia Pieria occupied an awkward political position throughout this period — nominally Seleucid, then briefly independent, then under Tigranes of Armenia from around 83 BC until Lucullus's campaigns drove him back in 69 BC. Civic bronzes like this chalkon were issued under local authority precisely because the city's overlordship was so unstable; no one power maintained enough control to monopolize small-denomination coinage. The Lindgren III and HGC attributions both place this type within the broader collapse of Seleucid administrative reach in northern Syria.
