From 2006, the Reserve Bank of India issued notes with a * (Star) after the first 3 characters or prefix followed by the six digit serial number. These are used as replacement notes for errors in printing. These were issued initially in denominations of 10, 20, 50. From 2009 star or replacement notes are issued for 100. The star series notes are identical to the existing banknotes in every respect except in the serial number where a * (star) is added in between the prefix and the serial number. For example 9AA*034801. The prefix in the star notes are unique to the star notes only and these prefix are not combined with the regular issues. When issued in a packet, it has a wrapper stating “contains non-serially numbered notes with * in the number panel”.
