1984-D Thicker LIBERTY and Date?

[Guest]

Needs some help, I am trying to compare some extra thickness on this 1984-D on the LIBERTY and Date. I hope the photos are clear enough. Labeled them Thick for the ones I think are thicker and normal to what I had as a "normal" coin.

But the "extra thickness" gets me. Not always sure but this one feels like it.

It is thick. Start by comparing the details, then mintmark location then markers to see if it matches any of the listed ones.

Thanks GrumpyEd. I will do that. I was starting to and decided to see if my thickness feeling was correct.

It looks normal for the date MM to me....at least in that I see a bunch of them that look thick.

Interesting. Now I will have to pay attention. I have set those aside for now and will look at the next round.

I have set those aside for now and will look at the next round.

That is always a good thing to do.

I think liberty is thick, about as thick as some of the listed ones. The date is about normal.
I do see a lot of 84s that are thick, they might not be doubled dies or not listable ones.

Always be safe to put it aside.

I agree this is a tough year...I also expect to see a little distortion before I start comparing on CC

I think that we are placing to much value on the term "extra thickness" to accurately describe a doubled die. If a design element has extra thickness in all quadrants, it is more than likely not a doubled die but a worn die. If a design element has extra thickness in one direction (or in some rare cases two directions), then it may very well be a doubled die. So, to further expand the term extra thickness, it should have the adjective "distorted" attached, or "distorted extra thickness". This term will suffice to accurately describe what is seen on a design element to qualify it as a possible doubled die.

All good info. I will hang onto it and look at it with fresh eyes and more coins.
