This is a one rupee note that has been professionally graded 64 UNC — an uncirculated example carried through third-party grading and sealed with a certified condition score. The note comes with its own recorded serial number, and the grade is what sets it apart from an ordinary one rupee note.
Grading matters because condition, more than almost anything else, drives what a collector will pay. A certified 64 sits in the choice-uncirculated range, meaning the paper is crisp, the corners sharp and the note free of the wear that circulation leaves behind. Buyers value the independent verification a grade provides.
What a graded one rupee note is worth depends on the grade itself, the issue and signatory, and the serial number — a higher grade or a scarcer issue lifts the price. Coinbazzar lists this verified graded note, and you can view it in the video before you buy.
