Tetradrachm; Gondophares IV Sases

Gondophares IV Sases ruled the eastern remnant of Indo-Parthian territory during a period when the kingdom was fragmenting under sustained Kushana pressure from the north. His tetradrachms in billon reflect that decline — earlier Indo-Parthian issues were struck in far purer silver, and the progressive debasement visible across this dynasty's coinage tracks the erosion of both trade revenues and political control over the Indus valley routes.

Senior 242 is one of the better-documented attributions in a series that remains genuinely difficult to sequence, partly because multiple rulers used the dynastic name Gondophares.
