Answer: Sher Shah

Sher Shah Suri

Shēr Shāh Sūrī (1486–22 May 1545), born Farīd Khān, was the founder of the Suri Empire in the northern part of the Indian subcontinent, with its capital at Delhi. An ethnic Pashtun, Sher Shah took control of the Mughal Empire in 1538. After his accidental death in 1545, his son Islam Shah became his successor.

The system of tri-metalism which came to characterize Mughal coinage was introduced by Sher Shah. While the term rūpya had previously been used as a generic term for any silver coin, during his rule the term rūpee came to be used as the name for a silver coin of a standard weight of 178 grains, which was the precursor of the modern rupee. Rupee is today used as the national currency in India, Indonesia, Maldives, Mauritius, Nepal, Pakistan, Seychelles, Sri Lanka among other countries. Gold coins called the Mohur weighing 169 grains and copper coins called Paisa were also minted by his government.
