More than one face on indian rupees

India is a large country with a long history. Many individuals have contributed in shaping the glorious history of this nation. However, all Indian currency notes bear the face of just one person. Even much smaller nations can find several individuals to honor in their currencies. My list of individuals consists as follows

1) Rani Lakshmibai (a hero from from India's first war of independence).
2) Sardar Vallabhai Patel (the person behind formation of Republic of India)
3) Dr B. R. Ambedkar (the architect of Indian constitution)
4) Dr A P J Kalam (a symbol of modern India)
5) Mahatma Gandhi (father of the nation)

Thus, the proposal is we retain (5) on one one denomination and (1) - (4) on each of the
other denominations. As a rule I propose that we must not include former prime ministers
in the list.
