1/2 Dirham - Güyük Khan

Güyük's reign lasted under three years — he died in 1248, likely from alcoholism aggravated by an arduous westward march, before reaching a confrontation with Batu Khan of the Golden Horde that most contemporaries considered inevitable. Coins issued under his authority are consequently among the scarcest of all Great Khan issues, minted across a brief window at workshops inherited from his father Ögedei.

The fractional denomination points to active commercial use in urban Central Asian markets, where Mongol administrators had learned to sustain the existing Islamic monetary infrastructure rather than replace it.
