Sher Shah issued coins in silver and copper and eliminated billon from the series of Indian coins.
The word Mohur was introduced by Sher Shah Suri during his brief rule. It was used for the gold coin weighing 169 grains. His other innovation was the introduction of Dam and a silver coin called ‘Rupiya’ that weighed 178 grains.
Sher shah commenced his coinage with silver tankas and rupees. The weight of these found to be varied. Several provincial mints were set up, which continued coinage of his predecessors as well. Most of his coins were mintless initially only from 1541 A.D. onwards names of mints were included.
