[Lee Stewart]

A "star" on a bill means it's a replacement for one with an error. When an imperfection is detected on a bill after a serial number has already been overprinted, the Bureau of Engraving and Printing replaces it with a "star note" before it goes into circulation. A star note is a note with the same serial number with an asterisk added to the end of it. These bills are more scarce than notes with traditional serial numbers, but carry the exact same value as any other dollar.
