The most expensive stamp in the world is the Treskilling Yellow that sold for $2.5 million Swiss Francs in 1996. Issued in Sweden in 1855 a normal three skilling stamp was printed in green while the eight skilling stamp was yellow. Due to an unknown error the three skilling stamp was printed in yellow, creating the Treskilling Yellow Stamp. The Treskilling Yellow was discovered by a schoolboy named Georg Wilhelm Baeckman in 1886 while going through his grandparents' attic. This is the only known copy in existence.Project 2
