Great Britain King George V 1924 2d Orange (No Watermark), SG421a.
A very fine unmounted mint full original gum left hand marginal block of four of this scarce watermark variety. Exhibition quality.
Accompanied with a 2009 British Philatelic Association Certificate of Authenticity.
The Stanley Gibbons catalogue price for a single stamp is £2,250. No premium is therefore attached to the price to reflect substantial higher rarity factor from being a block of four, in pristine condition and with left hand margin.
