Muhammad bin Tughlaq, the Sultan of Delhi, modelled the token currency system using copper and brass coins after China`s example. China had been using token currency for centuries before it was introduced in India. The use of token currency was believed to provide financial stability and prevent counterfeit coins from circulating. The system involved issuing coins made of cheaper metals like copper and brass, which were given a nominal value. This helped in controlling the supply of coins and maintaining their authenticity. While the use of token currency was an innovative concept, its implementation under Muhammad bin Tughlaq`s reign was not successful due to various reasons, including the scarcity of precious metal coins and the lack of acceptance among the common people.
