This is the old 20 rupee Parliament issue, a first issue signed by S. Jagannathan and catalogued as E-1. It carries the "Closed Lotus" variety, and some examples come with an "a" prefix in the serial — a detail that separates one note from another for specialist collectors.
First-issue notes and early signature combinations are among the more sought-after pieces of Indian paper money, because they mark the start of a series and were printed for a limited window. The Closed Lotus variety and prefix differences add further collecting interest on top of the design itself.
As always, value depends on the grade, the exact variety and the prefix — a high-collectable-grade note stands above a worn one. Coinbazzar lists verified examples with images, so you can confirm the signature, catalog number and condition before buying.
