The postage stamp world's rarest

Some postage stamps, come to reach impressive values, because there are few specimens.

It is the case of this, called "Magenta penny," issued by the British colony of Guyana, in 1856.

It presents the image of a boat and the slogan "We give and expect in return."

Some years ago, the Sotheby's auction house sold Magenta penny to an anonymous collector for $ 9.5 million.

The previous owner was a murderer, John E. DuPont, convicted of murdering an Olympic wrestler and died in prison in 2010.
