The 10 Rupee "Peacock" issue is a much-loved older Republic India note, known to collectors as the "Peacock" issue after its design. This is a full serial-wise bundle of 100 notes in UNC condition, and the issue is found in more than one governor signature and inset variety.
Peacock-issue bundles are sought after because the design is one of the more attractive older ₹10 notes, and finding a complete, uncirculated bundle in running serial order is harder than turning up a single note. The signatory and inset letter both matter to collectors chasing specific varieties.
Value depends on the signature, inset, grade and how intact the serial run is, so two Peacock bundles can differ widely in price. Coinbazzar lists verified UNC bundles so you can buy the exact packet featured in the video with its variety and condition confirmed.
