Drachm - Vologases IV Ecbatana

Vologases IV ruled the Parthian Empire through one of its most turbulent stretches — his reign included the catastrophic Roman invasion under Lucius Verus in 161–166 AD, which ended with the sack of Ctesiphon and a plague carried back westward that killed millions across the Roman world. The Ecbatana mint, ancient even by Parthian standards, served as a secondary striking facility and its output from this reign tends toward thinner flans with characteristic die-axis inconsistencies well documented across the Sellwood 84 series.
