The lifecycle and cost of a banknote
What is the average age of Indian currency? How often are our notes retired, and what is the cost of printing?
At the time of writing, my wallet has 10 notes bearing the signature of Reserve Bank of India (RBI) governor Raghuram Rajan, another 10 notes bearing the signature of his predecessor D. Subbarao (who retired in 2013) and one note bearing the signature of Subbarao’s predecessor Y.V. Reddy, who was RBI governor between 2003 and 2008.
