Indian 100-rupee note

The Indian 100-rupee banknote (₹100) is a denomination of the Indian rupee. It has been in continuous production since Reserve Bank of India took over the functions of the controller of currency in India in 1935. The present ₹100 banknote in circulation is a part of the Mahatma Gandhi New Series (which replaced the Mahatma Gandhi Series of ₹100 in 2018).

History
The first 100-rupee note featured the portrait of George VI. After independence in 1947, Reserve Bank of India continued to issue the notes by replacing the portrait of George VI with the Emblem of India, as a part of the Lion Capital Series of banknotes.

Design
The ₹100 banknote of the Mahatma Gandhi Series is 157 × 73 mm blue-green coloured, with the obverse side featuring a portrait of Mahatma Gandhi with a signature of the governor of Reserve Bank of India.

As of 2012, the new ₹ sign has been incorporated into banknote of ₹100. In January 2014 RBI announced that it would be withdrawing from circulation all banknotes printed prior to 2005 by 31 March 2014. The deadline was later extended to 1 January 2015, and then again to 30 June 2016.
