Great Britain 1p Black #1 Plate Error?

Hello all Stamp Masters,

I was checking out this Penny Black, and noticed that on the top right corner, to the left of the maltese cross, there seems to be a disturbance in the ink.
In other words: There is ink missing, a white hole if you will.

Also: In the black background, to the top right of the head, on top of the bun, there seem to also be errors in the ink.

Would these be actual plate errors?

What is the consensus here?

Would this add value? Or detract value?

It looks like an example from plate 7. It is quite far cut into the bottom of the stamp. That lowers the value considerably.

This is not a listed constant flaw. Maybe it is wear. This plate is known for that. The paper where the ink is missing looks whiter than the margins and the red ink of the Maltese Cross also appears to be missing here. Have you checked whether it is the ink that is missing or the surface that is missing?

The foot of the T and the right of the top loop in the S also have white spots. The spot at the foot of the T looks like a break in the cancellation as well.

The NW and NE rays of the right-hand star look suspicious.

Thanks for the information!
So I looked at the specimen under a magnifying glass.
It looks as though the red ink of the cancel covers part of the blemish, as marked below:

Btw, why do you say that the NW and NE rays of the right-hand star look suspicious?

Yes. On my screen, they show a much deeper black than the remainder of that star. They also continue outside the frame, especially the NW ray. That one looks as if someone used a pen to redraw the ray.

Also, the SW part of the area that you outline and where the red of the Maltese Cross is visible, it looks as if the background is black and not whitish.

Perhaps a scan of the back would point toward a possible repair?

OP included a scan of the back in his original post.

The missing ink on the stamp will most likely be from plate wear I'd say.

I agree with NSK, plate 7.
