Who issued a token currency in copper coins between AD 1329 and 1330?

Solution (By Examveda Team)

Tughlaq’s silver coin was named Adi. However, it was difficult to maintain the supply of gold and silver coins on a large scale. So, Tughlaq replaced those coins and started the circulation of copper and brass coins as the token currency which had the same value of gold or silver coins in 1330-32 CE.
