Drachm - Yazdgird II

Yazdgird II spent much of his reign in active military campaigning — first against the Byzantines in the early 430s, then pivoting decisively eastward against the Kidarites along the empire's Bactrian frontier. The coins struck during this window, roughly 439–447, correspond to a period when Sasanian administrative attention was sharply focused on the northeast, and mint output reflects that military economy.

The SNS reference PBW3#Ib1/2b designates a specific obverse die pairing documented by Schindel's corpus — the combination of bust type Ib1 with reverse die 2b is one of the more precisely catalogued attributions in this reign's sequence.
