The Inverted Jenny stamp is one of the rarest and most valuable US stamps. In fact, there is no philatelist that hasn’t at least heard about it. This stamp was printed in May 1918 and it was immediately named Inverted Jenny due to the recognizable upside-down image of the Curtiss JN-4 biplane.
Most of these stamps were destroyed, the exception is a single sheet of 100 stamps that was sold by a postal clerk in Washington. However, no one proved this mythical theory so we still don’t know the exact number.

Throughout the 19th century, the US printed various stamps with Benjamin Franklin’s face on them, yet these aren’t worth much today. However, the tables have turned with the collection of Benjamin Franklin’s “Z Grills”.
These stamps were created with a “Z” punch which has the purpose of keeping the ink in indentations to make reuse impossible. Unfortunately, these weren’t very effective, so they were recalled in 1870.
A great thing is that only a very few pieces survived, to be more precise only two! One example is at the New York City Public Library, and the other is in a private collection. The owner bought it in 2005 for almost $3 million.

If you take a good look you’ll notice that the center of the stamp consists of a miniature masterpiece, where a creator was able to engrave 42 persons! Also, the six principal figures can be recognized under a magnifying glass!
This two-colored independence stamp features a face value of 24 cents and comes in three different variations – split, double grill, or G grill. However, what makes this stamp super valuable is the fact it comes with a major error, the center image of the stamp was inverted! It is believed that only four stamps like this exist nowadays.

Current prices of some of the most valuable stamps you can find on the market
There are a lot more valuable stamps in the US as well as worldwide, besides the stamps we mentioned above. This is why we decided to make a list of stamps that are leading in prices on the global stamp market and not just in the US.
How To Determine The Value Of The US Stamps
This can be hard if you don’t know any basic information, but if you are willing to learn determining the value can be relatively easy to do. Here is what you need to pay attention to:
- Do the research – Find as many printed books or guides as you can and use them as a reference. Make sure you figure out the age and the material it was used this will significantly help you form a final price. Also, observing the centering of the design is very important, any error in this part can raise the value.
- Assess the condition – Try to figure out which grade your stamp has. Remember there are three grade levels for stamps – sound (in perfect condition), faulty (with small damages), or defective (if it has stains, abrasions if it misses a corner, and so on).
- Look for watermarks – Look for watermarks like quarterfoil, lozenges, or network. These are made to prevent counterfeiting. Remember, the lozenge watermark looks like small diamonds, and only a very few have it, while most have network watermarks.
- Check if the stamp is labeled as rare or if it has some valuable error – Rare errors, or rare designs in the philately world are a big money maker. We talk about millions of dollars! Research the internet, books, and forums, and consult an appraiser before selling. We recommend to look at Stamp World.
What error US stamps are valuable?
The unique imperfections create extreme value, but to be able to recognize an error stamp you need to learn how to spot those flaws. The main reason why stamps with printing errors are so attractive to collectors is their uniqueness.
Did you know that some errors can result in increased value by thousands of times more than normal?! Here is a list of some of the most common eros that can occur on US stamps:
- Design error – Occurs when during the design phase of production the design gets messed up in range from a minor mistake (missing letter in the name) to more serious errors (wrong picture of a subject, out of date maps, misspelled text).
- Denomination error – Occurs when during the printing process a stamp gets a wrong denomination printed.
- Omission error – If a part of the design is missing that is called omission error. The reason why it occurs is a fault in the design stage of production.
- Overprint error – When a text, denomination, or image gets printed twice or more times on the same stamp an overprint occurs. Overprint errors can significantly raise the value of a stamp.
- Inverted overprint – When the overprint is placed upside down compared to a regular design scheme.
- Wrong overprint – When an overprint intended for another stamp is used incorrectly.
- Double impression – When a stamp or overprint of the same design is printed twice, and one impression ends up slightly offset from the other.
- Invert errors – Invert errors are an end result when one or more elements of a postage stamp’s design are printed upside down. There are two basic types of this error an inverted frame and an inverted center.
- Color error – This occurs when a stamp ends up printed in the wrong color or when one or more of the intended colors are missing.
- Color shift error – A color shift error occurs when one (or more) of the printing cylinders are out of function and end up causing overlapping of the colors.
- Missing color error – Logically, when one or more colors are missing, it is usually because something during the multi-run printing process went wrong.
- Watermark errors – Watermarks are used to prevent counterfeiting. The watermark process can often result in errors like inverted, sideways, or missing watermarks. These are very sought-after among collectors.
- Paper error – When a stamp is printed on the wrong type of paper that may have a different watermark, color, or thickness.
- Imperforate errors – Perforations are small holes you see on a block of stamps. They enable an easier separation. Sometimes a rare error occurs when perforations are missing from one or several sides.
- Offset error – This is a minor mistake, and it can be identified easily. You’ll notice a regular impression on the stamp’s front yet an offset reversed impression on the reverse side.
- Inking errors – This one is pretty obvious and occurs when too much ink is applied or too little ink is applied. These mistakes can make the design look unrecognizable
- Albino error – Sometimes a complete inking stage is missed, and we get a stamp with a blank impression or printed image with no color only borderlines.
- Miscuts – These errors happen when a stamp sheet is misaligned with the blades. Miscuts can result in just a few millimeters being clipped off or a complete design. This is most common in coil stamps.
How to recognize an authentic US stamp?
It’s useful to know what to look for in stamps to be able to determine if they are real or fake. Pay attention to the following and you’ll be able to recognize a replica with ease.
- Watermarks – Every stamp has a watermark that is difficult to reproduce. They differ by country and act as a “stamp” of approval. If there is no watermark or it looks different the stamp is fake.
- False postmarks – Look for the cancel mark carefully, most canceled stamps are fake.
- Regumming – Forgers will try to “regum” stamps to make them look as real as possible.
- Perforation – The perforation around a stamp can help you a lot to recognize replica. If it is modified or removed something might be off. Most stamps are first gummed and then perforated. If they are first perforated and then gummed then they are fake.
- Quality – Look for the quality of paper used, and attention to fine details.
