Fractional Dinar - Muhammad I

The Alamut State — the Nizari Ismaili polity headquartered in the Alborz mountain fortresses of northern Persia — produced coinage intermittently and often in fractional denominations, partly because the isolated castle economies it served had little use for full-weight dinars. Muhammad I, imam from roughly 1138 to 1162, ruled during a period of relative consolidation after decades of open conflict with the Seljuq sultanate. Gold issues attributable to his imamate are genuinely rare; most surviving Alamut coinage is silver or of disputed attribution.
