The system of tri-metalism which came to characterize Mughal coinage was introduced by Sher Shah. While the term rupya had previously been used as a generic term for any silver coin, during his rule the term rupiya 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 Pakistan, India, Ne-
pal, Sri Lanka, Indonesia, Mauritius, Maldives, Seychelles among other countries. Gold coins called the Mohur weighing 169 grains and copper coins called Dam were also minted by his government.
