Ala ud din Khliji issued coins in gold, silver, copper, and billon. Gold and silver tankas issued by him are very common and were struck at three places: Delhi, Dar al-Islam, and Deogir. He also struck some square tankas in both metals, but they did not have the mint name inscribed on them. Alauddin Khalji minted coins with the legend Sikander Sani. Sikander is Old Persian for 'victor', a title popularised by Alexander. While sani is Arabic for second, the coin legend (Sikander-e-Sani) translates to 'Second Alexnder' in recognition of his military success. His coins omitted the mention of the Khalifa, replacing it with the self-laudatory title Sikander-us-sani Yamin-ul-Khilafat.
