A replacement banknote, identifiable by a star symbol appended to its serial number, is issued when a note is damaged or misprinted during the production process. This star signifies that the note is a substitute for one removed from circulation and ensures the correct quantity of notes within a given series. For instance, if a sheet of uncut $100 bills is damaged, the flawed notes are removed, and replacements with star-marked serial numbers are printed and inserted to complete the sheet.
The value of these replacement notes varies. While most circulate at face value, some can be quite valuable to collectors, especially rare or low-print-run star notes. The Bureau of Engraving and Printing’s practice of replacing flawed currency maintains the integrity of the money supply and provides a fascinating area of study for numismatists. This practice has a long history, contributing to the rich tapestry of American currency and providing insight into the printing and distribution processes.
