This is the 500 Rupee note of 2012, carrying the signature of Reserve Bank Governor Subbarao and the Dandi March reverse used on the old ₹500 series. Collectors track it in two forms — the Inset E variety and the plain-inset variety.
An inset is a small letter printed within the number panel; its presence or absence marks a different print run, so a single year can yield more than one collectable note. An uncirculated (UNC) example, still crisp and unhandled, is the most sought-after state, because the great majority of ₹500 notes from this period were spent rather than saved.
Value turns on the inset variety, the serial number and the grade — a genuine UNC note is worth more than a folded, circulated one. Coinbazzar lists verified 2012 Subbarao ₹500 notes in both inset types, so you can match the exact variety before buying; the live price appears on the listing above.
