  • Mahtma Gandhi (MG) Series 1996

Are there any special features in the banknotes of Mahatma Gandhi series- 1996?

The Mahatma Gandhi series-1996 banknotes contained several special features vis-à-vis the banknotes issued earlier. These are

    1. Security thread: Rs.10, Rs.20 and Rs.50 notes contain fully embedded security thread. Rs.100, Rs.500 and Rs.1000 banknotes contain windowed security thread. This thread is partially exposed and partially embedded. When held against light, this thread can be seen as one continuous line. Other than on Rs.1000 banknotes, this thread contains the words ‘Bharat’ in the Devanagari script and ‘RBI’ appearing alternately. The security thread of the Rs.1000 banknote contains the inscription ‘Bharat’ in the Devanagari script, ‘1000’ and ‘RBI’.
    2. Latent Image:  The vertical band next to the (right side)  Mahatma Gandhi’s portrait,  contains a latent image, showing the denominational value 20, 50, 100, 500 or 1000 as the case may be. The value can be seen only when the banknote is held horizontally  and light allowed to fall on it at 45° ; otherwise this feature appears only as a vertical band.
    3. Micro letterings: This feature appears between the vertical band and Mahatma Gandhi portrait. It contains the word ‘RBI’ in Rs.10. Notes of Rs.20 and above also contain the denominational value of the banknotes. This feature can be seen better under a magnifying glass.
    4. Identification mark:A special intaglio feature (raised printing) has been introduced on the left of the watermark window, on the obverse (front) on all banknotes except Rs.10/- banknote. This feature is in different shapes for various denominations (Rs.20-Vertical Rectangle, Rs.50-Square, Rs.100-Triangle, Rs.500-Circle, Rs.1000-Diamond) and helps the visually impaired to identify the denomination

    5. Intaglio Printing: The portrait of Mahatma Gandhi, Reserve Bank seal, Guarantee and promise clause, Ashoka Pillar Emblem  and RBI Governor’s signature are printed in intaglio i.e. in raised prints in Rs.20, Rs.50, Rs.100, Rs.500 and Rs.1000 banknotes.
    1. Fluorescence: The number panels of the banknotes are printed in fluorescent ink. The banknotes also have optical fibres. Both can be seen when the banknotes are exposed to ultra-violet lamp.
    1. Optically Variable Ink: The numeral 500 & 1000 on the Rs.500 [revised colour scheme of mild yellow, mauve and brown] and Rs.1000 banknotes are printed in Optically Variable Ink viz., a colour-shifting ink. The colour of these numerals appears green when the banknotes are held flat but would change to blue when the banknotes are held at an angle.
  1. Watermark:    The banknotes contain the Mahatma Gandhi watermark with a light and shade effect and multi-directional lines in the watermark window.
