Real Picture, Proving The Value Of An X-Topic

I would like to show the most accurate pictures, I tried to message them to the moderator but I think here is more better,
the first attached picture showing the real stamp in my album, 2d & 3rd showing it on my hand from both sides, obviously the printed letters appeared, letter on the stamp's face are prominent you can touch & feel them by fingers.

It appears to be carefully cut out from a postal stationery envelope. Perhaps someone with a catalog of such items can provide you with more specific information, such as date(s) of issue and size of envelope(s).

The gum arabic on the back proves nothing more than someone used (or re-used) this item to avoid paying postage. This has been done commonly.

sherifsaleh the only way to convince anyone that this is "rare" is to send it off for certification to prove that it's not just a cutout from a postal stationery envelope which had some sort of glue applied in order to adhere it to a regular envelope.

The embossing is standard and the glue remaining is possibly due to the fact that the cutout was affixed to the envelope only in the center and was later torn off (instead of being soaked).

I don't think anyone here will agree with your assessment, but in any event, you will need proof from a philatelic organization to prove us wrong.

Suggestion.
If the fragment is gummed, perhaps it is from the flap of a registered mail envelope?
Higgins and Gage members may have confirmation.

Tip: You should be handling the piece with tongs, not your fingers Sir.
