1/2 Dinar ' Mithqal' - 'Ali Mu'ayyad

The Sarbedaran were a peculiar formation — a Shi'a rebel state that emerged in Khorasan in the 1330s, nominally vassals of the Ilkhanate but functionally independent after Mongol power collapsed in the region. 'Ali Mu'ayyad, who ruled from roughly 1364 to 1386, was the dynasty's longest-reigning and most capable leader, eventually submitting to Timur without significant resistance around 1381 rather than face destruction. That political calculation preserved Sabzevar from the massacre Timur inflicted on less cooperative cities.

Gold coinage from the Sarbedaran is extremely rare in any denomination — a minor regional power with limited access to bullion supplies left a thin documentary record in metal.
