The Mahatma Gandhi Series of banknotes are issued by the Reserve Bank of India as the legal tender of Indian rupee. As the name suggests, 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 has replaced all issued banknotes. The Reserve Bank of India (RBI) introduced the series in 1996 with the 10 and 500 banknotes. At present, the RBI issues banknotes in denominations from 5 to 1000. Printing of five-notes, which had stopped earlier, restarted in 2009. ATMs usually dispense 100, 500, and 1000 notes. ==Security features== The following features are included in the notes.〔(Reserve Bank of India Currency Frequently Asked Questions (FAQ) ) 9th Jan, 2012〕 * Secure thread : The notes contain an embedded security thread that can be seen as a vertical straight line when held against light.
