Clarification On Halfpenny.

Hello, the anomalous cut on this stamp because on both sides in a semicircular way? Has anyone cut it like this? Sorry for grammar errors, I use a translator. Thanks.

Probably destroyed when being cut from an envelope with scissors. Or possibly a sheet was cut with scissors in an office before use.

Or it could be a coil stamp that was miscut by a dispenser or vending machine. George V's coils have perforations all around; they're distinguished from sheet stamps by watermark.

One would think that a vending machine uses a straight blade ?

Thanks for your answers. The question that it was cut with scissors in my opinion seems to exclude, it would make no sense to cut it that way. I have never seen a stamp cut that way, I hope to be proved wrong, but it seems machine error.

An undiscovered error for decades makes more sense to you than the simplest explanation that it was cut with scissors? Always start with the assumption that you have the most common stamps and do not undiscovered stamps. (You have multiple threads where you assume that you have errors and rare stamps, none of which have been.)

I agree with the direction codehappy is going. Your stamp is watermarked sideways - an indication of a coil.

It is easier to use an arced or diagonal cut in an affixer or vending machine to cut across the coil web rather than chopping through the entire web at once. Thus also the consistency of the arc on both sides. This particular blade was likely arced (think like a sharpened spoon) to slit first from the center then both upward and downward simultaneously to complete the full separation.

This item has every characteristic of a machine-affixed coil stamp, slightly out of adjustment by the end-user. I see no error.

I joined the forum because, being inexperienced in the subject, I was looking for answers on stamps that, not having so much knowledge and little study material, seemed to me stamps with defects. someone in the forum these questions annoy.I thought of leaving the forum thanking you for your courtesy.Un warm greeting.

Forgot to say that I don't try to enrich myself with stamps and I've never talked about rare stamps, but only to have clarifications.
