Picture Updates For 1983 D DDR?

The issue with the polished die has nothing to do with it being a variety. Even variety dies get polished when event happen that alter the die. (clashes, die dents and ETC) But here is what I'm talking about:
Here is a nickel that the die was so polished away (center image) that the tip of the 'G' is missing and the overall size of the devices are thinner. This is because the field was reduced and part of the wide taper of that letter was reduced, making these letters smaller

This one is over polished on the bust. So now parts of the face are missing.

Here is a case where the die edge was polished down unevenly and not the letters look tapered:

Same thing on this proof die:


That is why the images of your coins devices looked thinner that the examples I posted. So I still see nothing like hub doubling on your coin. Normal die and the coin has some contact marks on the top of the devices on some letters. Nothing enlarged like the 1983 DDRs.

This is new to me - thanks for mentioning it. I wonder if anyone has more information about this?

I think slamn is right. The devices are the normal size, so I kind of ruled out hub doubling a while ago. Now just trying to figure out what this is so we can use it for future knowledge.
