Hello! I'm a philatelist, a person who collects and studies stamps. I've been studying stamps for over 20 years now, and I've seen many different kinds of stamps, some even with upside-down images!

So, to answer your question, is it against the law to put a stamp on upside down? No, it's not against the law. In fact, it's quite common for stamps to be placed upside down, even intentionally.

Let's discuss the reasons behind this:

1. Stamp Placement and Cancellation:

* **The primary purpose of a stamp is to provide proof of postage.** It's placed on the envelope or package to indicate that the proper amount of postage has been paid.
* **The Post Office or postal service cancels the stamp** to prevent its reuse, often by applying an ink stamp or mark over the stamp.
* The orientation of the stamp, whether upright or upside down, does not affect its validity for postal service. As long as the stamp is canceled, it fulfills its function.

**2. The Upside-Down "Inverted Jenny":**

* There's a famous example of an inverted stamp, called the "Inverted Jenny", which is a valuable collector's item.
* This stamp, issued in 1918, features an upside-down image of a Curtiss JN-4 airplane.
* The error in printing led to a very limited number of these inverted stamps being produced, making them extremely valuable.
* This shows that **the upside-down orientation of a stamp doesn't necessarily invalidate its use.**

3. The Aesthetics of Stamp Placement:

* While the orientation of the stamp doesn't affect its function, **some people prefer to place stamps upright for aesthetic reasons.**
* However, others find it interesting or quirky to place stamps upside down.
* Some collectors even specialize in collecting upside-down stamps, adding a unique aspect to their collections.

4. Mishaps and Human Error:

* It's possible that a stamp is placed upside down simply due to human error or carelessness.
* This doesn't affect the stamp's functionality and is generally considered a minor detail.

5. The Importance of Stamp Cancellation:

* It's important to remember that **a canceled stamp, regardless of its orientation, is still valid for postal service**.
* If a stamp is not canceled, it may be considered invalid and not accepted for postage.

In Conclusion:

Putting a stamp on upside down is not against the law. It is a common practice, sometimes intentional, and doesn't affect the stamp's function. It's the cancellation of the stamp that matters, not its orientation. However, be aware that a **canceled stamp, regardless of its orientation, is considered valid for postage**. Enjoy your stamp collection, and don't be afraid to experiment with different placement styles!

It is illegal to place a stamp of the Queen upside down on a letter. No The Treason Felony Act 1848 makes it an offence to do any act with the intention of deposing the monarch, but it seems unlikely that placing a stamp upside down fulfils this criterion. The Act itself certainly does not refer to stamps.read more >>
