1861 2d dull rose Queen Victoria Horizontal Pair, Perforated 9 Horizontally, Imperforate Vertically, unused (no gum), with a thin and a crease at top centre and a bit of light soiling, fine. Accompanied by a 2017 Greene Foundation certificate. Although the certificate identifies this pair as a #1c (imperforate between, of which we are aware of three examples in existence), no examples of the 2d imperforate vertically have been recorded other than the example offered here from the Crosby collection. A rare opportunity to acquire a unique major error from the Queen Victoria era. (Image)

1863 3d blue on Cover to Nova Scotia, mailed on APR.2.1863 (large PRINCE EDWARD ISLAND c.d.s.), through Halifax (APR.8), Lunenburg (APR.8) then Bridgewater (APR.9). A lovely inter-Colonial cover, with a very fine stamp and four different clear datestamps on back (listed above). Very fine and undervalued in Unitrade. Ex. Dale and Wilkinson and accompanied by certificates from The Philatelic Foundation (New York, 1966) and The Greene Foundation (2015). (Property of a different vendor) (Image)

Unitrade $ 1,200

1861 3d blue Queen Victoria, Perforated 9, with Double Impression of the entire design. Unused (no gum), exceptionally well centered with bright fresh colour and intact perforations, with a small thin (not mentioned in the accompanying 2017 Greene Foundation certificate). Based on our research, we are aware of only four other single examples of this major error, at least one of which was part of the Jephcott horizontal strip of three. The Crosby example offered here is by far the best centered example, and has full intact perforations; the small thin is irrelevant as all of the single stamps mentioned above have thins (in addition to cracked gum, ragged perfs, poor centering, etc.). The Crosby example is by far the most attractive example recorded. (Image)
