Iltutmish introduced Silver Tanka and Copper Jital, the two coins of the Delhi Sultanate. The coins prior to Iltutmish were introduced by the invaders, which bore the Sanskrit characters and even Hindu Gods, Bull and Shivalinga. For example, Muhammad Ghori is known to have adopted the seated goddess Lakshmi type of the coins of Gahadavalas for circulation in the Gahadavala territories. Iltutmish was the first to introduce a “Pure Arabic Coin” in India. The Silver Tanka issued by Iltutmish weighed 175 grains. Balban later issued gold Tanka of the same weight.
