Dinar - Mu'izz al-din Muhammad b. Sam Bayana mint

The Bayana mint sat at a strategically critical node in the eastern Gangetic plain, and its activation under Mu'izz al-din — better known in later historiography as Muhammad of Ghor — followed directly from the Ghurid victory at the Second Battle of Tarain in 1192, which effectively ended Rajput resistance and opened northern India to permanent Ghurid administration. Gold dinars from this mint are among the earliest Islamic gold coinages struck on Indian soil under a conquering dynasty rather than a tributary arrangement.

The weight standard reflects a deliberate negotiation between the traditional Ghurid mithqal and the local suvarna, a compromise that would shape Indo-Islamic monetary practice for generations after Mu'izz al-din's assassination in 1206.
