Drachm

Istros, a Milesian colony on the western Black Sea coast near the Danube delta, issued this drachm during a period of intense commercial pressure from Macedonian expansion under Philip II and later Alexander. The city's coinage served trade networks reaching deep into Thracian and Scythian territories where Greek silver was actively sought as a medium of exchange rather than a store of wealth — meaning these coins circulated hard.

The AMNG I-I#434 reference places this within Imhoof-Blumer and Pick's foundational Black Sea corpus, still the primary typological framework for Istrian coinage after more than a century.
