Bactria's pre-Alexandrian coinage remains one of the least-documented areas in Greek numismatics. Issues from this period predate the Macedonian conquest of 329–327 BC and the subsequent Seleucid administrative reorganization, meaning attribution to any specific mint — Bactra, Taxila, or otherwise — is largely inferential. The weight standard here aligns with the Achaemenid-influenced reduced Attic system common to the eastern satrapies, not the Aeginetan or full Attic standards of the western Greek world.
