The 100 Rupee "white stripes" Dam Issue is one of India's classic older banknote types, known to collectors as the "Dam" issue after the dam design associated with it. This offering is a set of four notes, each carrying a different governor's signature from the years the note was in issue.
Collectors seek a matched signature set because assembling several governor varieties of a single design in one lot is harder than finding a single note. Each signature marks a distinct period of issue, so a run of them tells the story of the note across its lifetime.
Value on any Dam Issue note depends heavily on grade, paper quality and which signature you hold, so two notes of the same design can sit far apart in price. Coinbazzar lists verified pieces so you can inspect the condition before buying the set featured in the video.
