1 Dinar - al-Hasan b. al-Firuzan Sari

Al-Hasan b. al-Firuzan was a Buyid-era local governor operating in the Daylam and Gilan regions of northern Iran, and his coinage represents one of the more obscure expressions of delegated minting authority in the fragmented Abbasid world. The Firuzanids held power in Sari — the principal city of Tabaristan — during a period when the Buyids themselves were consolidating control over the caliphate, making even nominal independent coin issues a politically loaded act.

Gold dinars from provincial governors of this tier and period are genuinely rare survivors.
