One of the rarest known stamps, the “Treskilling Yellow” — or three-shilling stamp — was issued by mistake during a print run of eight-skilling stamps, which are yellow. The three-skilling was normally green.
A Swedish schoolboy stumbled upon it in 1885 while rummaging for stamps to sell for pocket money. Since then it has passed through the hands of a series of stamp collectors.
