A Swedish "Treskilling" stamp circa 1855 recently surpassed a $331,000 stamp from the Chinese Quing Dynasty as the world's most expensive stamp. Interestingly, the stamp isn't even a perfect example of its kind - the value stems partly from its yellow color, and the fact that this is the only example of its kind ever found, says Paul Nelson, vice chair of the Postal History Foundation in Tucson, Arizona. The Treskilling, or Tre Skilling, as it is also known, should be green. It was last sold for $2.3 million in 1996.
At just 0.02675 grams, the Treskilling stamp is also considered the world's most valuable item by weight. This week, you can find the stamp in Islington, London, where it is on display at the Festival of Stamps. It is expected to fetch more than $7.4 million at auction on May 22 in Switzerland.
