Mithridates III ruled during a period of acute dynastic instability — his reign ended when he was deposed and imprisoned by his brother Gotarzes I, who had briefly held power before him. The succession disputes of this era left physical traces in the coinage: dies were often reused or hastily cut, and Sellwood 40.3 in particular is known from a relatively limited die pool, making die-linked specimens of genuine documentary interest to specialists in Arsacid numismatics.
