Babur, the founder of the Mughal dynasty, was a descendant of Timur and Genghis Khan. One of the ways in which he pledged his allegiance was by introducing the Shahrukhi denomination of coin to the Subcontinent. Shahrukhis were flat, round silver coins first issued by the Timurid ruler Shah Rukh in the 15th century. These coins had a good run in India under Humayun and Akbar until they were replaced by the rupee. Babur was born a prince in Ferghana, present-day Uzbekistan, with ambitions to rule Samarkand. When he failed to hold onto his throne there, he came eastward and, after the Battle of Panipat in 1526, invaded Agra and Delhi. This silver coin weighs nearly 5 grammes, and on the obverse it features the Kalima (the Islamic invocation to Allah) and the names of the four caliphs. On the reverse, it has the date the coin was minted (Hijri year 910, 1504–1505 AD), the mint town (Badakhshan), and the name of the emperor. Generally speaking, Shahrukhis issued by Babur would carry the lengthy legend of: Al-Sultan Al-Azam Wa Al-Khakan Al-Mukarram Zahiruddin Muhammad Babur Badshah Ghazi. The obverse has a cartouche inside that is inscribed Kalima Reverse. The reverse mentions the date, mint town, and name of the emperor.
