Great Britain 1882 1d lilac I.R. Official Die II, unused unique imperforate block of three, SGO3ca
A very fine unused, with original gum, imperforate irregular block of three formed from a vertical pair and a single example. Some light ink marks on vertical pair, nevertheless a unique piece from the 8th printing of July 1891 with overprint in blue-black and as such previously unrecorded. The vertical pair was formerly erroneously listed in the Stanley Gibbons GB specialised catalogue as L3f - ""Imperforate without watermark"". There is infact a light, very misplaced watermark. It is to be listed in the next specialised catalogue as L3f ""Imperforate with blue-black overprint"". and is now included in the Stanley Gibbons GB Concise catalogue as SGO3ca. Accompanied with a 2015 British Philatelic Association (BPA) Certificate of Authenticity. Stanley Gibbons catalogue value: £9,000+.
