The law of March 13, 1932 stipulated that until the return to normal economic situation and the stability of the possibility of paying with gold or gold-based foreign currency suspended due to the economic crisis, the National Bank (Bank Melli Iran) was allowed to receive no silver coins or paper money in circulation which may be offered with a gold purchase (coin, bullion, or foreign currency). However, Bank Melli should pay Rial cash against paper money and nickel coins if there is a demand without limitation, for each coin in either Tehran or other provinces.
