Tetradrachm - Hermaeus Soter and Calliope

Hermaeus was almost certainly the last Indo-Greek king to issue silver coinage of any significance, ruling in the Paropamisadae region as Bactrian Greek power collapsed under Saka and Yuezhi pressure from the north. His joint issues with Calliope — likely his queen — are unusual within the Indo-Greek series, where consort coinage is rare and politically deliberate. The pairing suggests a dynastic legitimacy claim at a moment when such claims were fragile at best.

After his reign, his image was appropriated and restruck by the very Kushan rulers who displaced him, producing posthumous issues well into the first century AD.
