The 5 rupee Tractor issue note — named for its reverse showing a farmer ploughing with a tractor — is a favourite among Indian banknote collectors. The pieces featured here carry the auspicious 786 in their serial number. The tractor note ran for years and was signed by several different RBI Governors over that time, so the exact signatory varies from note to note.
The number 786 is treated as auspicious by many collectors, so notes whose serials contain or end in 786 change hands for well above face value. A stronger pattern, such as a repeating or solid number, is scarcer still. Grade matters too: a clean, uncirculated note is worth more than one in used condition, even with the same serial. Because pricing turns on the exact number pattern and the note's condition, no two examples are quite alike.
