SAFAVID: Isma'il II, 1576-1578, AV ½ mithqal (2.32g), Qazwin, AH98(4), A-2612, couplet "If there is an Imam from east to west, 'Ali and his family sufficeth for us" replaces the kalima and names of the 12 Imams on the reverse, unique to this short-lived ruler for the Safavid dynasty (reference to the Imam 'Ali b. Abi Talib), excellent strike, VF, RRR. Very few gold coins of Isma'il II are known, and in addition to this piece, I know of only one from Isfahan and two from Simnan, all of the half mithqal denomination.
