What do you mean by duplicate? A star note, or replacement note, and was made by the U.S. government to replace another bill that never reached circulation due to printing errors.
the duplicate star notes from the 2013 B series They were printed twice, in both Washington and Fort Worth. I have now found 2 of them. I just don't have the matches.
it has happened for other people, maybe I will find my matches as well. I posted one of them on the 2013 B site but no hits yet. I'm about to add the second one now.
