THE FINER OF ONLY TWO KNOWN EXAMPLES OF THE 1857 3-CENT PERFORATED ISSUE WITH DOUBLE IMPRESSION. THIS IS ALSO THE ONLY 1857-60 ISSUE KNOWN WITH A DOUBLE IMPRESSION. A GREAT RARITY.
Our census and summary of Double Impressions is included as an appendix to this catalogue. Most double impressions occur when the first impression is made and found to be inadequate. The paper is then put in the press a second time, where it receives the heavier impression. It is a common misconception that the weaker impression is the second one.
A review of philatelic literature, Philatelic Foundation records and past auction catalogues located only this example and one on cover certified as genuine double impressions. Both are illustrated below and are available at our website at http://www.siegelauctions.com/dynamic/census/26e/26e.pdf . None is known unused.
Ex Piller and Wagshal. With 1985 and 2010 P.F. certificates.
