Chalkon - Seleukos II Kallinikos Magnesia on the Maeander

Seleukos II inherited a fractured empire in 246 BC, immediately facing war on two fronts: Ptolemy III invaded from the west in the Third Syrian War while his own brother Antiochos Hierax rebelled and seized Anatolia. The Magnesia on the Maeander mint was operating squarely within that contested Anatolian zone, meaning this bronze issue was produced under conditions of genuine political instability rather than consolidated Seleucid authority.

Kallinikos — "nobly victorious" — was an epithet applied somewhat generously, as Seleukos never fully recovered the eastern satrapies lost to Arsakes I during the Parthian revolt of circa 238 BC.
