Interesting fact: Do you know what is star series note?Many of us are aware that production of bank notes is a very complicated process. It involves several steps. Let us suppose, RBI is going to print Rs. 100/- notes. These are issued in bundles of Rs. 100/- notes in a serial order. If, during the process of production, any error occurs disturbing the continuity of the series, the defective notes are then replaced. In place of those defective notes, star series notes are issued. Star series notes are inserted replacing the defective notes in the bundle, which are arranged in a sequential order. Star series notes have a star symbol in the number panel. As for example, a star series note will have the number in the following pattern – 1AA*012345. In star series notes, there will be a prefix of three characters before the symbol (*), and six digits after the symbol. The present star series has been introduced by RBI in 2006.
