VERY FINE BLOCK OF THE UNISSUED 1860 1-1/2-PENNY ROSY MAUVE. AN IMMENSE RARITY OF THE LINE-ENGRAVED PERIOD AND THE LARGEST KNOWN MULTIPLE IN PRIVATE HANDS.
This stamp was printed and prepared for use in 1860 in anticipation of a change in postal rates. Changes did not come to fruition, but some 10,000 sheets were already printed. Most of the supply was destroyed and it is unknown how or why unused examples managed to get out with three or four even postally used. Postal changes did occur about a decade later in 1870, whereby SG Nos. 51/52 were issued using the same plates.
A block of six is the largest recorded multiple known in private hands. We are aware of only two other blocks of six - D-J to E-L (ex Beresford) and R-F to S-H. It goes without saying that multiples of any size are extraordinarily rare.
Ex Adams and Baillie. With 2005 B.P.A. certificate. Catalogued simply as hinged singles. SG £51,000. Scott $52,500.00.
