Ma Huan
Shēr Shāh of northern India issued silver currency bearing Islamic motifs, later imitated by the Mughal empire. The Chinese merchant Ma Huan (1413–51) noted that gold coins, known as "fanam", were issued in Cochin and weighed a total of one "fen" and one "li" according to the Chinese standards. They were of fine quality and could be exchanged in China for 15 silver coins of four-"li" weight each.
