Q. The token currency using copper and brass coins was modelled after which country’s example by Muhammedbin Tuglaq?
Answer: China
Notes: Muhammad bin Tughluq introduced token currency inspired by Kublai Khan and Ghazan Khan, issuing copper and brass coins to match the silver tanka's value. Poor control and counterfeiting caused the failure of this system. He also drew from China's paper money practice but used metal due to India's lack of paper-making technology.
