The number 786 carries special significance for many collectors, and Indian banknotes bearing it in the serial are among the most sought-after fancy-number pieces. Examples span several denominations, including a Rs 10 note with a 000786 serial and a Rs 100 note with a 786786 repeater arrangement, both in Gem UNC condition.
Fancy-number notes like these are collected for the pattern itself rather than the face value, so demand is driven by how clean and rare the serial is. A holy or repeated number in crisp, uncirculated grade will always sit at the top of the range, while circulated examples fetch less.
What a 786 note is worth depends on the denomination, the exact number pattern and the grade. Coinbazzar lists verified 786 fancy-number notes so you can see the current asking price on the piece featured in this video.
