Drachm - Yazdgerd III

Yazdgerd III came to the throne in 632 as a teenager, installed by a faction of nobles desperate to hold the empire together after years of catastrophic civil war and plague had gutted both the treasury and the army. He never controlled more than fragments of what his predecessors had ruled. The Arab conquest began within months of his coronation, and by the time coins of his later regnal years were being struck, the mints were moving with the court — fleeing east as province after province fell.

This early issue, struck just three years into his reign, predates the fall of Ctesiphon in 637.
