Post-mint applied mintmark on Peace dollars?

[one iota]

Can anyone confirm this type of illegal mintmark application?

The mintmark seems to be sub-micro, often not centered between the rays, and most importantly resides at the bottom of a concave dome.
They exhibit every sign of a post-mint punched mintmark.
Ultra small to affect the least amount of movement to the metal.
Alignment off because they were punched individually.
The surrounding dome allows for the metal to displace into the mintmark.

Picture of whole coin, thanks. What year ? Looks added .

Year please?
Full coin images?

Hello again.
i apologize for being so latent posting these requested images.
It took me forever to figure out that the reflection of my finger improved the visual depth of the inverted dome.

I don't have any idea of what's going on here................

Only one coin per post and mint marks where not the same for every year, use vamwrold.com to look up mint mark types.

I see nothing abnormal in the mint marks you post.

A depression is not uncommon around a mint mark.

Your 1924's S mint mark took a hit so it got deformed somewhat.

Back then a number of different mint mark punches were used during the same year of production. The marks were had punched into the dies back then, so the location of the mark varies - even within the same year.

Click on each picture in turn and use the large view to compare your 1927-S mint mark with all those listed, then do the same for the other dates.

Thank you Earle42 for your response.
I can understand the variance in the position of the mintmark, but the surrounding indentation still baffles.

I can understand that there would be an indentation around the mintmark on the die, but wouldn’t that transfer to the coin as a raised dome?

I’m off for more education via the links you and Mr. Moderator (Daniel, i think) kindly provided.
Thanks again.

The Mintmark here HAS NOT been added after the minting of this coin......

Small depressions around Mintmark's are quite common.....

Keep in mind that these tiny letters are hand punched into the die, causing a slightly raised area adjacent to that punch ......
When the coin is struck, this raised area will appear as a small depression.

Thank you Paul. That’s good to know.
I was assuming that the mintmark punches had a small blank field surrounding the letter, like line-o-type lead letters, except not square-ish, but i suppose that would create more of a rim around the mintmark.
I guess a slight dome is better.
Thank you for following up.
Hoping my next post to be more fun for you.

What Paul said is correct.
But for a bit of clarification in light of your last post: When you punch the letter's impression into the metal, the force of punching has to displace the metal at the point of impact in order to allow the image of the mint mark to become embedded in the die. Sometimes there would be a bulging around the position of the newly formed imprinted letter as the metal was displaced in a more upward direction. Sometimes the moved metal could displace thoguht being compacted into the surrounding metal.
Movement/compaction would depend on uniformity of the metal's density at the point of impact. Obviously the bulge would make a depression, as stated.
