What is a fifty dollar bill with a star on it worth?

Answer 1

If has a relatively new date (e.g. 1996 or later) it might be worth a few dollars above face value to a collector of "star notes".

If it's older, please post a new question with the bill's date and whether there is a small letter next to the date.

Answer 2

A fifty dollar bill with a star on it typically indicates that it is a replacement note. Its value is the same as a regular fifty dollar bill, depending on its condition and demand in the collector's market.
