Error Stamps: An error stamp is a stamp that has some kind of mistake. This could mean that it is unhinged or a detail on the stamp is incorrect. Stamps that aren’t usually valuable can become very much so if they contain errors.

The Benjamin Franklin 1908 Stamp: This rare one cent stamp, when found unused and hinged in perfect condition, can be worth $100,000!

1868 Canadian Stamp: This two-cent ultra rare stamp features a picture of Queen Victoria. There are only two of these stamps that are known to be in existence today!

Hawaiian Missionary Stamps: These stamps are the state of Hawaii’s very first stamps and are known as Missionary Issue. There were four stamps originally issued, with three values: two cents, five cents, and thirteen cents. It is almost impossible to find these stamps in undamaged condition.

1911 25c Vin Fiz Airpost Stamp: There are only 12 of these stamps recorded to be in existence. The only example shown to go to a foreign destination fetched $88,000!

British Guiana One Cent Magenta Stamp: This amazing rarity is probably the most valuable stamp in the world. It was first discovered in 1873, and auctioned to millionaire John Dupont for over $900,000. There is only one other known copy of this stamp in the world, which is currently undergoing tests for authenticity.

Swedish Three Skilling Banco: These stamps were normally made in green, but in 1885 a yellow stamp was found that was deemed to be a printing error. In 1996, this stamp sold for over two million dollars!
