A note with an asterisk (*) or star following the serial numbers is referred to as a star note. Before US paper money is released as available for general circulation, the Bureau of Engraving and Printing examined it for printing mistakes. Since there were no duplicated notes within a given series that may be manufactured with the same serial numbers, notes that have been printed erroneously are pulled out from printing processing and replaced with star notes when they are found (for example, when the serial numbers are printed incorrectly, etc.).
They are used to maintain a correct count of notes in a serial number run. By their nature, star notes are extremely scarcer than notes with standard serial numbers and as such are widely collected by numismatists. Some of the highest prices paid for modern U.S. banknotes have been for star notes.
