⅙ 'Sudaysi' Dirham - al-Muti'

Al-Muti' became caliph in 946 under circumstances that stripped the office of nearly all executive power — the Buyid amir Ahmad ibn Buya (Mu'izz al-Dawla) entered Baghdad that same year and reduced the caliph to a ceremonial figurehead, the first time an Abbasid ruler had been so openly subordinated to a temporal power. Coinage continued in the caliph's name as a matter of religious legitimacy, since the Buyids, being Shia, still required Sunni caliphal authority on coin and in the khutba to maintain broader acceptance.

The sudaysi fraction — one-sixth of a dirham — reflects the fragmented small-denomination silver economy of mid-tenth-century Iraq, where full dirhams had become too valuable for everyday transactions in a contracting monetary environment.
