Lot 40101 – 1840 1d black pl.4 KI-KK strip of three, four margins and part of KH to left, cancelled by Maltese crosses in red

1840 1d black pl.4 KI-KK strip of three, four good margins with part of KH to left, clean crisp printing, cancelled by red Maltese crosses, a very fine example with an exceptionally clean back and no faults; cert. Brandon (2011) and signed by Holcombe and Sorani in pencil on the reverse. Note: strips of three are rare and the catalogue value for a pair on this plate is £1’250; strips like this are more than four times less common and although there are no catalogue values attributed to such items it is reasonable to say that a four margin fault free example should be evaluated at a cv of around £6’000.
