The note in this video is a vintage ₹500 Dandi March issue, an older high-denomination note carrying the famous image of the 1930 salt march to Dandi. It is a design collectors associate with one of the most historic motifs used on Indian currency.
Older ₹500 Dandi March notes are sought after because the high face value meant fewer were set aside in collectable condition, so clean vintage examples are scarcer than everyday circulated ones. Value on a note like this turns on the signatory, the series and inset, and the grade — an uncirculated, well-centred piece sits well above a folded, handled one.
