World’s most expensive stamp sold

The world’s most expensive postage stamp, a one-of-its-kind issue printed in Sweden in 1857, was sold at auction in Geneva to an international consortium on Saturday, auctioneers said.

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.
