A copper coin of Madras and vicinity, issued early in the eigteenth century, and of a value of twenty Cash, or Kas.
On a Madras copper of 1801 the obverse has an Arabic inscription indicating its value to be two Falus, and the reverse inscription is partly in English and partly in Telugu, stating a value of two Dubs. The Dub and the Falus may therefore be considered as synonymous.
In 1794 a one forty-eighth copper Rupee was struck by the United East India Company for the Circars, a large district on the coast of the Bay of Bengal to the north of the Carnatic country. In this coin an attempt was made to assimilate the Muhammadan with the Hindu monetary system, as the forty-eighth part of a Rupee is just equal to the peice of twenty Kas.
