The roupie or rupee was the currency of French India. It was equal to the Indian rupee issued by the Indian government. One rupee was worth 2.40 francs-or. Until 1871 it was issued as coins with the roupie divided into 8 fanons, each of 3 doudous or 20 cash. From 1891, banknotes were issued by the Banque de l'Indochine, which circulated alongside coins issued by British India.
