Drachm - Diomedes

Diomedes is one of the more obscure Indo-Greek kings, known almost entirely through his coinage rather than any surviving literary record. He ruled a fragment of the collapsing Baktrian Greek world during the late 2nd to early 1st century BC, a period when the Indo-Greek kingdoms had splintered into a patchwork of competing dynasts, many controlling little more than a mint town and its hinterland. His bilingual issues — Greek on one side, Kharoshthi on the other — confirm he operated east of the Hindu Kush, likely in the Paropamisadae or Gandhara region.

Bopearachchi places him in a relatively tight chronological bracket based on die linkages to neighboring rulers rather than any fixed historical anchor.
