ICELAND – 1902-03, 20a blue with red overprint stamp – worth US.$.8,500

20a blue with red overprint is one of the most impressive Icelandic stamps that are definitely worth collectors’ attention. It is so scarce because of an overprint error (it had to be ’02-’03 instead of 02′-’03). The specimens without such a mistake and perforated 14 x 13 ½, was offered by Spink at its auction that took place on May 16, 2008 with 1986 Svendsen certificate fetched $8,500.
