Great Britain 1840 1d black Plate 1a, SG2Great Britain 1840 1d black, plate 1a lettered 'JI', SG2. A very fine used example with four good to large margins, cancelled by red Maltese Cross. Plate 1 of the penny black was put to press on 11 April 1840 and registered on 15 April 1840. As the plate had not been hardened in a rush to meet the target issue date it soon showed signs of wear.
