1861-70 No wmk 1s blue, rough perf. 14-16, ERROR OF COLOUR, unused, penstroke removed as usual, perforation or traces thereof on three sides (SG £18’000) A fresh and most attractive example of this rarity Expertise: Cert. BPA (1976) Provenance: Ferrary, Hind Note: In 1863 the printers, Perkins, Bacon & Co., sent a supply of 50’000 to the island. On arrival it was discovered that they were printed in blue, the colour of the 1d, instead of black. A new supply was dispatched and the “blue” error was not put on sale. Before disposing of these stamps, a number were removed and defaced with a cross in ink which has subsequently been cleaned. It is believed that only nine such error exist
