6 pieces in set. <strong>VERY RARE</strong> and seldom seen Specimen set. The opportunity to acquire these pieces is quite exciting. All notes have a finely perforated "SPECIMEN" across the face, which to many is preferred in comparison to the distracting bold red or black overprints that typically come printed on top of Specimen issues. All notes are problem-free with the exception of a little bit of toning on a few and 50 Mark, which has minor archival rust as mentioned on the holder. A set like this is not likely to appear on the market again for quite some time..PCGSBG Choice About Uncirculated 58 to Gem Uncirculated 65 Details.
