Lot of (3) Fr. 2079-E. 1993 $20 Federal Reserve Note. Richmond. About Uncirculated. Book End Notes. Paper Jam Error. An unusual error in any respect, this dramatic error is representative of a paper jam error. The note in question appears almost "caked" in regard to its nature with crumpled sections of the note fully printed. Two bookend notes are included for posterity and serve as companion pieces to this dramatic and unusual error.
