India's Rs 1 note, which first came into production in 1917, completes a century on November 30.
The government had stopped printing the grey-coloured note with the symbol of Ashoka Pillar in 1994 but resumed printing on public demand in
2015.
The design of the note has been changed 28 times in 100 years.
The Rs 1 currency is the only one which bears the signature of the finance secretary and not the governor of the Reserve Bank of India.
