which ruler issued the first rupiya in country
Rupee Rūpiya was first named to a silver coin weighing 178 grains (11.53 g) minted in northern India by Emperor Sher Shah Suri during his brief rule between 1540 and 1545.[3] Suri also introduced copper coins called dam and gold coins called mohur that weighed 169 grains (10.95 g).[4]
Satavahana dynasty The Satavahana power was revived by Gautamiputra Satakarni, who is considered the greatest of the Satavahana rulers.[34] Charles Higham dates his reign c. 103 – c. 127 CE.[34] S. Nagaraju dates it 106–130 CE.[42] The king defeated by him appears to have been the Western Kshatrapa ruler Nahapana, as suggested by Nahapana's coins overstuck with names and titles of Gautamiputra.[41] The Nashik prashasti inscription of Gautamiputra's mother Gautami Balashri, dated to the 20th year after his death, records his achievements. The most liberal interpretation of the inscription suggests that his kingdom extended from the present-day Rajasthan in the north to Krishna river in the south, and from Saurashtra in the west to Kalinga in the east. He assumed the titles Raja-Raja (King of Kings) and Maharaja (Great King), and was described as the Lord of Vindhya.[9]
