Dinar - Wahram IV Merv mint

Wahram IV ruled for only a decade (388–399) and left an unusually thin documentary record for a Sasanian king, his reign sandwiched between the better-attested Shapur III and Yazdegerd I. The Merv mint — deep in Margiana, far from the Ctesiphon heartland — served primarily as a supply point for campaigns on the northeastern frontier, where Kidarite pressure was a persistent and largely underdocumented problem throughout the late fourth century.

SNS Iran#Ia3/1a places this among the earliest die groups of the reign.
