Dinar - Yazdgerd II lightweight

Yazdgerd II ruled during a period of sustained military pressure on both frontiers — campaigns against the Eastern Romans in the west and the Kidarites in the east — and his reign also saw aggressive suppression of Christianity in the empire's Armenian territories. The "lightweight" designation reflects a deliberate reduction from the standard Sasanian dinar weight, a fiscal adjustment documented across his issues and likely tied to the costs of continuous campaigning.
