<P> A star note is also a bank note that has an asterisk (*), or star, after the serial number . Many early issues carried the star in front of the serial number . These have been used by various countries around the world including Australia and the United States . 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 more scarce than notes with standard serial numbers and as such are widely collected by numismatists . Some of the highest prices paid for modern (post-1928) U.S. banknotes have been for star notes . </P> <P> A star note was also substituted for the last note in a block rather than printing a note with a serial number consisting of eight zeros . This practice is no longer in use, as the highest range of serial numbers is now reserved for uncut sheets sold to collectors, so regular notes intended for circulation do not reach the final serial number in the block . </P>
