In 1918, the United States Postal Service issued a 24-cent stamp featuring a Curtiss JN-4 airplane in honor of the first transcontinental airmail flight. Unfortunately, a few stamps were printed with the airplane inverted due to a printing error. Today, only 86 of these so-called “inverted Jennies” are known to exist, making them among the most valuable stamps in the world.

Originally the stamp was sold for just $0.24, but it was later sold at auction for a staggering $2.7 million – making it the most valuable U.S. stamp ever.

The New York Library holds the other example. The “Blue Boy” stamp gets its name from its blue coloration, which was created using a printing process that was new at the time. The Z Grill printing method was used to avoid the deceit of reusing the stamp.

The stamps were printed on thin paper and were perforated with 11 gauge holes. There are two varieties of stamps, one with “Hawaiian Missionary” and the other with “Postage Paid.” The “Hawaiian Missionary” variety is the most valuable, with a single stamp selling for over $619500.

The Almanac stamp was worth 3 cents in the early years. According to a recent auction, the stamp in pristine condition was sold for $2,576,600.

8. 1860 Stolen Pony Cover

The Stolen Pony Cover gets its name from the story behind its creation. The American Express company was founded in 1852 to provide express shipping services nationwide. In 1860, one of their riders was carrying a shipment of mail when he disappeared. The mail was later recovered from a Native American tribe, and one of the stamps on the envelope was a 3-cent Pony Express stamp.

This stamp is now known as the 1860 Stolen Pony Cover and is considered one of the most valuable U.S. stamps. The other letter was sold at auction in 1876 for $1,000 – making it the most expensive stamp ever sold at that time. Today, both examples of the Stolen Pony Cover are housed in private collections worth millions of dollars each.

9. Pan American Inverts

There are many types of inverts, but the most famous and valuable is the Pan-American Invert. This invert was issued in 1901 to commemorate the Pan-American Exposition in Buffalo, New York. The stamp's center depicts the exposition's logo, while the outer ring contains images of all the participating countries.

The Pan-American Invert is so valuable because only 100 known examples exist. Of those 100 examples, only two are in mint condition. The rest have been damaged or canceled. Even if you can find one of these stamps, it will likely cost you at least $50,000.

10. CIA Invert

CIA Invert

The “CIA Invert” is a United States postage stamp issued in May of 1968 to commemorate the 100th anniversary of the Central Intelligence Agency. The stamp features an image of the CIA seal, with the eagle facing inwards instead of outwards.

This error was not caught until after the stamps had been printed, and as a result, only 100 of these stamps were ever sold. These stamps are now some of the most valuable in the world, with some examples selling for over $1 million.

How to Discern Valuable Stamps?

To the casual observer, all stamps may appear to be of similar value. However, several factors can affect a stamp's value, making some more valuable. Knowing how to discern valuable symbols from their less useful counterparts is essential if you're interested in collecting stamps.

Here are a few things to keep in mind when trying to determine the value of a stamp:

  • Issuing authority: Stamps issued by government entities are usually more valuable than those issued by private companies or individuals.
  • Age: Generally, older stamps are more valuable than newer ones. This is because they are rarer and have been around longer, increasing their collectible value.
  • Condition: The condition of a stamp can also have a significant impact on its value. A stamp in pristine condition will be worth more than one damaged or well-used.
  • Face value: The face value of a stamp also affects its overall value. A higher denomination stamp is typically worth more than a lower denomination one.

With some knowledge, you'll discern which stamps are valuable and which aren't worth your time and money.
