Throughout history, the right to Coinage and Currency and issues of sovereignty have been curiously conjoined, emotionally if not rationally; these issues stimulate debate even today. The transition of currency management from colonial to independent India was a reasonably smooth affair. Midnight, August 15, 1947 heralded Indian independence from colonial rule. The Republic, however, was established on 26th January, 1950. During the interregnum, the Reserve Bank continued to issue the extant notes.
Government of India brought out the new design Re 1 note in 1949.
Government of India - Rupee OneSymbols for independent India had to be chosen. At the outset it was felt that the King's portrait be replaced by a portrait of Mahatma Gandhi. Designs were prepared to that effect. In the final analysis, the consensus moved to the choice of the Lion Capital at Sarnath in lieu of the Gandhi Portrait. The new design of notes were largely along earlier lines.
Rupees Ten - King's Portrait
Rupees Ten - Ashoka PillarIn 1953, Hindi was displayed prominently on the new notes. The debate regarding the Hindi plural of Rupaya was settled in favour of Rupiye. High denomination notes (Rs 1,000, Rs. 5,000, Rs. 10,000) were reintroduced in 1954.
Rupees One Thousand - Tanjore Temple
Rupees Five Thousand - Gateway of India
Rupees Ten Thousand - Lion Capital, Ashoka PillarThe lean period of the early sixties led to considerations of economy and the sizes of notes were reduced in 1967. In 1969 a commemorative design series in honour of the birth centenary celebrations of Mahatma Gandhi was issued depicting a seated Gandhi with the Sevagram Ashram as the backdrop.
Rupees One Hundred - Commemorative DesignCost benefit considerations prompted the Bank to introduce Rs. 20 denomination notes in 1972 and Rs. 50 in 1975.
Rupees Twenty
Rupees FiftyHigh denomination notes were once again demonetised in 1978 for the same reasons as the 1946 demonetisation. The 1980s saw a completely new set of notes issued. The motifs on these notes marked a departure form the earlier motifs. The emphasis lay on symbols of Science & Technology (Aryabhatta on the Rs 2 note), Progress (the Oil Rig on Re 1 and Farm Mechanisation on Rs 5) and a change in orientation to Indian Art forms on the Rs 20 and the Rs 10 notes.

Management of Currency had to cope with the rising demands of a growing economy, together with a fall in purchasing power. The Rupee 500 note was introduced in October 1987 with the portrait of Mahatma Gandhi. The water mark continued to be the Lion Capital, Ashoka Pillar.

With the advancement of reprographic techniques, traditional security features were deemed inadequate. It was necessary to introduce new features and a new 'Mahatma Gandhi Series' was introduced in 1996. A changed watermark, windowed security thread, latent image and intaglio features for the visually handicapped are amongst the new features.
