20 Qirsh - Abdullah

The Mahdist State operated its mint at Omdurman under conditions of near-constant military siege, and coinage production was subordinate to the demands of a theocratic war economy. These large billon pieces were struck during the reign of Khalifa Abdallahi, who succeeded the Mahdi Muhammad Ahmad after his death in 1885 and struggled throughout his rule to maintain monetary credibility against a collapsing treasury. The .100 fine silver content reflects not a deliberate policy decision so much as chronic metal shortages.

The state fell to Kitchener's Anglo-Egyptian forces at the Battle of Omdurman in September 1898, ending the mint's output abruptly.
