Dinar - Yazdgerd I

Yazdgerd I is one of the more historically complex Sasanian rulers, remembered in Armenian and Syriac Christian sources with unusual warmth — he granted toleration to Christians within the empire and allowed church councils to convene, earning the epithet "the Sinner" from Zoroastrian priests who despised him for it. His reign coincided with extended peace with the Eastern Roman Empire, formalized in 409, which freed resources from the western frontier and likely contributed to relatively stable mint output.

The SNS Iran type III reference places this among the later issues of his reign, after administrative reforms consolidated minting under tighter royal oversight.
