On some notes, a star appears in place of the last letter. When an imperfect sheet is detected during the manufacturing process after the serial number has been overprinted, it must be replaced with a new sheet. A "star" sheet is used to replace the imperfect sheet. Reusing an exact serial number to replace an imperfect note is costly and time consuming. A "star" note has its own special serial number followed by a star in place of a suffix letter.
I hereby present another of my favorite collected US starred notes. People tend to disregard them, but chances are you might have a highly priced jewel in your collector's arks. Within my collection area there are several additional starred notes posted on this same blog's date. Feel free to check the various printing "perhaps" mistakes or hidden oddities.
