Tetradrachm - Seleukos II Kallinikos Teos

Seleukos II inherited a fractured empire: his reign opened with the Third Syrian War against Ptolemy III, who sacked Antioch and briefly occupied much of the Seleucid heartland. The Teos mint, on the Ionian coast, was among the western mints operating during this period of contested control, and its output reflects the urgent need to pay troops and administrators across a frontier that kept shifting.

The SC 644 series is well-documented by Houghton and Lorber, with die linkage studies showing relatively limited production runs from Teos compared to the major eastern mints.
