Excellent information! Thank you very much Glen 😎👍🏻

Now I have a clearer idea about where to put it in my collection! Greetings 👋

Your "size difference" stamps are fairly common. It is just a matter of poor quality control during the time of perforating. These would be considered "freaks" and not errors and therefore would not warrant a unique catalog number. I have included a scan of some of mine including a stamp that was so misaligned that someone had cut the stamp in order to center the design. They do however make for an interesting display for your collection. - Glen

Hello, I have the doubt if this variation in size is something that usually happens very common? Or if it's already something that should have a more special place among the collection?

If I take the measurement from the tips of the perforations, it is 30 millimeters high!

Greetings to everyone and Merry Christmas 2023
