Star Notes
When an imperfect note is detected during the manufacturing process after the serial number has been overprinted, it must be replaced with a new note. A "star" note is used to replace the imperfect note. Reusing that exact serial number to replace the imperfect note is costly and time consuming. The "star" note has its own special serial number followed by a star in place of a suffix letter.
The serial number of the imperfect note that was removed is not used again in the same numbering sequence.

The modern US five dollar bill (or note) does not have a red star on it. some older versions did carry a seal printed in red, but this would hardly be seen as a star.
A twenty dollar bill with a star on it can be worth different amounts depending on the date. A 1914 twenty dollar bill with a star on it is worth 1000 dollars.
A star on a dollar bill marks it as a "replacement note". If there's a problem printing a normal press run of dollar bills, then a series of replacement notes are issued. The star simply serves to identify them.
One dollar.
