Mohammad bin Tughlaq’s experiment of introducing token currency could not succeed on account of
- Rejection of token coins for purchases by foreign merchants
- Shortage of copper for mining token coins
- Large-scale minting of spurious coins
- Poor quality of token currency
Mohammad bin Tughlaq issued token currency - the coins of brass and copper were minted whose value were equal to gold and silver coins. This experiment failed because during his time, most of the citizens were gold-smiths and hence they knew how to make fake coins. As a result, the value of coins decreased.
