World's most expensive stamp has a price tag of 5m pounds !

The tiny Treskilling Yellow, weighing just 0.03 grams is worth a whopping 5 million pounds. The stamp, which will be auctioned off in Geneva next week, exists only because a 14-year-old Swedish schoolboy rescued it from his grandmother's rubbish bin in 1885 and sold it onto a dealer for the lowly price of seven Kroner.he three-shilling stamp was first issued in Sweden in 1855 and used in 1857 to mail a letter.

Its rarity is augmented by the fact that it was the only one in the batch to printed in yellow by mistake, when it should have been printed in green. The last sale was in 1996 when it sold for 2,875,000 Swiss Francs, to collectors who remain anonymous.

"There was hot competition when it was sold last time. People collecting stamps like to have rare things, like to have special things. I think maybe it's because it's been known for so many years, it's special," The Telegraph quoted Thomas Hoiland, a Danish auctioneer, as saying.
