The Gandhi Series of banknotes are issued by the Reserve Bank of India (RBI) as the legal tender of Indian rupee. The series is so called because the obverse of the banknotes prominently display the portrait of Mahatma Gandhi. Since its introduction in 1996, this series replaced all Lion Capital Series banknotes issued before 1996. The Reserve Bank of India (RBI) introduced the series in 1996 with 10 and 500 rupee banknotes.
