A star note is also a bank note that has an asterisk (*), or star, after the serial number. In the US, the Bureau of Engraving and Printing inspects currency for printing errors prior to releasing notes into general circulation. When notes are discovered that have been printed incorrectly (such as having the serial numbers upside down, etc.) the misprinted "error notes" are replaced with star notes because no two bills within a certain series can be produced with the same serial number.
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.
