Heinrich Köhler 383rd Auction – Day 1 - Single Lots: Europe and Colonies, incl. Great Britain and British Commonwealth, Overseas countries

30 Kr., so-called 'Rosa Merkur', type Ib, slightly touched on the right, otherwise wide to over-margined, unused with full, somewhat refreshed original gum and small paper remnants; the stamp colour unfortunately strongly faded. This stamp (postage stamp) is extremely scarce in unused condition, only a few pieces with original gum are known. One of the great scarces of classic philately. Certificate Ferchenbauer (1995)
