备注	The ₹ symbol printed on the reverse marks the clearest way to distinguish this series from its predecessor — India's official rupee sign was adopted in 2010 following a government design competition won by D. Udaya Kumar, and the RBI began incorporating it into new note designs shortly after. The presence or absence of a small square at the left of the obverse, combined with plate letters and three different governor signatures, produces an unusually fragmented signature matrix for a single Pick number — at least twelve catalogued varieties across a five-year run. Urjit Patel's signature variants here are among his last before demonetisation in November 2016 rendered the preceding ₹500 and ₹1000 notes void overnight, a policy that indirectly accelerated the design refresh leading to the Mahatma Gandhi New Series.
