Is this evidence of repairs to D/D/D die? NO. Answered

My theory is incorrect, as proved by others in later comments.
I theorize that this coin is en example of a D over horizontal D on a 1942 D Jefferson Nickel. Experts please explain or prove me wrong.
I see a more shallow area starting above the right lower base of Monticello and then dipping around the D. This is not happening on the other side of the building.
Notice inside the D a slightly crooked horizontal line at the upper inside of the D and the mess inside the D. There is one also along the lower inside. It almost looks like a rectangle in one pick with shadows.
The left side of the D has what appears to be an intentional HIT mushing metal over. I pose this area was the left exposed under mintmark. The coin shows heavy die polish lines all around the reverse.
To further complicate this situation with my imagination, I cannot find reliable cross reference photos clear enough to show die polish lines or scratches. In addition, on the 1953 D/D many examples have similar horizontal die polish lines visible in Monticello letters and around them.
Sorry for cell phone pictures it is all I have.

Here are the only pictures of true D/Horizontal from CoinFacts I could find. Variety vista only has mm close ups.

It does appear to be an RPM... though I cannot confirm the D over horizontal D... not from the pictures anyway.... ICBW.... Cheers, RickO
That is the D/Horizontal D. As to the first few photographs, I don't know if that was a deliberate attempt to repair the mint mark or normal everyday die repolishing.
I don't see it. I also don't completely NOT see it. I don't see the horizontal D at the left edge, but the hole does seem a bit squared up.
Is the assignment made on other die markers rather than the mintmark?
That's kind of funny because, I can see it kinda but then again I can't, makes absolutely no sense does it

If you first look at the location of the mintmark to the pillar below it, you will notice how the left side of the mintmark lines up almost perfectly with it.
The D/S coin exhibits the pillar lining up more towards the middle inside of the MM.
At least that's what it looks like to me.
Of course, check it out. I might not be seeing it correctly.

It appears to me that you have a double d but not the horizontal d style. I’ve often wondered how a horizontal d could ever have been nor do I know how many there are. The reason is I don’t collect varieties.
Great question my man. Stay with it and I’m sure you’ll be one of the best around.

I don't think it is. Like others have said, it might be repunched, but it isn't the horizontal D.
I've owned more than a few examples of the variety, and when you see it, you know it.
Here is my AU50 D/D. What I am thinking as a possibility, is that someone at mint saw the “defect” and tapped the exposed under D with a chisel or punch, moving away metal from the left side, essentially erasing it. After repair die was polished to smooth the area.

Furthermore, of the Three listed RPMs on 42 D, the other two bear no clear resemblance at all. I currently own examples of RPM 1 & 3
While RPM 3 shows a somewhat rectangular inner area the sides are not the same and inner top of D different

That doesn't work. The horizontal D is raised. You can't just chip away metal, you'll make the defect bigger not smaller. You could polish it down, but then the regular D should be getting weaker also.
Unless you think they polished it down and then repunched the D. In which case you have a brand new rare variety. LOL. But now you are asking for all kinds of repairs. Isn't it more likely that it's A D/vertical D (RPMs pretty common on nickels) or just a D with a die chip and polishing?
As others have said, not the horizontal but possibly a vertical D/D/D.
This makes sense. The area around the D would have a noticeable convex look instead of having the concave or dipping appearance I am seeing.
Metal would have to be added, not polished away, in the situation I originally described. Highly unlikely as you pointed out.
I was trying to imagine how things would look in reverse and forward with the die and the coin. That with the inexplicable hit the MM has on the left side.
Thank you

d, not polished away, in the situation I originally described. Highly unlikely as you pointed out.
Could be a D/D. I do find the amount of polishing interesting as well. This is why I hate most varieties. LOL. You get bleary eyed staring at them and then you still aren't sure which of 5 varieties it is!
That's for sure, that's for dang sure.
