Great Britain 1840 1d black, Plate 11, SG2.
A very fine used example with four good to large margins lettered HE, in the characteristic greyish black shade, cancelled by a black Maltese Cross.
A good quality example of the holy grail of penny black collecting, the elusive last printing plate. Only 168,000 were printed from this plate, representing a mere fraction of the total number of penny blacks printed of 68 million. Very few have survived from this plate number, particularly in fine condition.
The penny black represents a real landmark in British and worldwide history and this example is from the most sought after printing plate of them all.
Accompanied with a Royal Philatelic Society (RPS) certificate of authenticity (2004).
The SG catalogue value is £4,600.
