These are ₹1000 banknotes chased for their serial numbers as much as the denomination. One is a solid fancy number — 222222, every digit the same. The other is an ultra-low serial, 000001, the very first number in its run.
Solid numbers and single-digit low serials are among the most collectable fancy-number categories, because so few can exist in any print run — only one note in a series can be 000001, and repeating-digit numbers are equally scarce. Where a note has been assessed by a third-party grading service, that grade documents its condition and authenticity and adds buyer confidence.
Value depends heavily on the exact number, the signatory, the year and the grade; a solid 222222 or a 000001 sits far above an ordinary note. Coinbazzar lists verified ₹1000 fancy-number notes so you can see the number and grade before buying, with the live price on the listing above.
