Hi. Going thru more rolls and came across this. Vest caught my attention. What is this? I thought MD but its super raised. Ty in advance

Also, I took pics of front and back on phone but every time I try to log in on phone, it logs me out as soon as I get to forum so I can't post them. Microscope doesn't let me zoom out enough to take full coin pic.

Possibly been retooled. Let’s see what others have to say.

Resembles some of the die strengthening I noticed on a lot of 1936-42 proofs. Hardly seems worthwhile to take the time for a 1974-D cent die.

I wonder if it was a worn die that allowed the design on the edge in that area raise from the die deterioration

It does seem that the leading edge of Lincoln's coat was touched up on the working die. Such work typically was reserved for proofs, though the 1944-D half dollar with its AW monogram recut is another exception.

I'm not sure of this offers an explanation, but it's something I found on error-ref. Maybe something to consider

That's the correct explanation and wording for what I was meaning in my elementary explanation. I didn't know it had a name. Good to know.

Scroll through error-ref enough times and you begin to remember a lot of the pics ("you know, I saw something like that before").  However, it did take a little effort to find it again.
