Chalkous - Artabanos

Sophene occupied the upper Euphrates region as a semi-autonomous Armenian principality, and coinage attributed to an Artabanos in this period sits at the uncertain boundary between Achaemenid administrative tradition and early Hellenistic local dynastic assertion. The name Artabanos is Iranian in origin, common among ruling families across the former Persian satrapies in the decades following Alexander's conquests.

Alram 236 places this issue within a tightly defined dynastic sequence, though the chronological brackets remain disputed among specialists of Armenian numismatics.
