1859 Sicilian Error Of Color

The most famous stamp in Italian philatelic history is the Sicilian Error of Color, which was released in 1859. The stamp is extremely expensive because of a color misprint: it should have been printed in yellow, but the objects were manufactured in blue for unclear reasons. According to experts, only two copies of this historic stamp have survived.

In 1899, both artifacts were displayed at the Manchester Philatelic Exposition. Following that, these one-of-a-kind artifacts were separated and auctioned off as part of the famed Ferrary collection. The stamp's high worth is partly justified by its outstanding antiquity.

Despite its age, the Sicilian Error of Color has been conserved in excellent shape. This highly sought after antique stamp was auctioned off by Dreyfus in June 2011. The stamp cost 1.8 million euros to produce (approximately 2.6 million dollars). An online bidder from the United States won the lot. With this price, it is regarded as one of the most expensive postage stamps.

Price: $2.6 million
