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.
Focusing strictly on the $1 notes, they have been printed simultaneously at both Washington and Ft. Worth since the 1988-A series, each series with their own star note output. Is this project stating that only the 2013 series has overlap in the star note serials that allow this type of duplication? Or would it be possible on other series as well?
Serial numbers aren't supposed to be used more than once in the same series. This thread is about a specific serial number range in Series 2013 that was accidentally printed at both DC and FW, due to some kind of record-keeping failure. This isn't the first time that serial numbers have been duplicated by mistake, but it's the first time that the duplication has been widely publicized before most of the notes had already worn out in circulation. So it's the first time, as far as I know, that matched pairs have actually been found and brought together. Previous known instances of duplicated serial numbers on star notes include 1995 $1 B00000001* - B00640000*, 1995 $1 F09856001* - F10240000*, and 1999 $5 BE00000001* - BE00256000*. All of those printings took place at DC, not FW, so the duplicate printings have to be distinguished by plate numbers or plate positions. And none of those duplications were known to collectors until quite a few years after they had occurred, so no actual matched pairs were put together from any of them, that I've ever heard of.
Thanks @Numbers. That makes sense. So even if a series is printed in both locations, the serial numbers are supposed to be split between the two facilities. It's not a case where Washington would print A0000001* to A9999999* and Ft. Worth would have it's own set of the same numbers. Instead, it would be something along the lines of Washington would print #1 to 500K and Ft. Worth would print 501K to 999K (or some other similar breakdown). I've learned something new!
