The denomination remained in usage through the Mughal, Maratha, East India company and British rules.^[2][3] The rupiya was retained by the East India company till 1835 and formed the basis of the British Raj currency till 1947.^[4] Each rupiya coin weighed 178 grains (11.5 grams). The sub-unit of rupyia were copper pieces and 40 copper pieces constituted as one rupiya. Sher Shah Suri named the copper pieces as Paisa.^[2][4][5]
