Tetradrachm

Choresmia — the oasis kingdom centered on the lower Amu Darya delta in what is now Uzbekistan and Turkmenistan — operated largely outside the orbit of both the Seleucid and Parthian empires, maintaining a distinct monetary tradition that borrowed heavily from Hellenistic weight standards while developing increasingly local iconographic vocabulary. The tetradrachm series referenced by Mitchiner 1587–1590 spans a period during which Chorasmian rulers asserted genuine independence, issuing coinage in their own name at a time when neighboring regions were absorbed into the Parthian sphere.

The silver used in these pieces is notably debased compared to contemporary Parthian issues, suggesting local smelting from regional sources rather than refined imported bullion.
