1984 D Washington Quarter odd finish. What happened here?

[Blancarte88]

I found this 1984 D quarter and it has an odd finish. I looked it up online to see if I could identify it and I couldn't find anything. Can anyone help? The pics show the texture of the metal all the way across the obverse and the reverse all the way to the very edge of the coin. How does this happen? Is it an error? Thank you ahead of time for your help.

It looks like it had a bath in acid or some other corrosive liquid.

Are you positive that this texture isn't consistent with what is referred to as "Orange peel texture" which is caused when a die experiences microscopic plastic flow and the die suffers from deterioration or die deformation at the end of its life?

I forgot to also note the the texture doesn't seem to of ended up on the sides of the coin. See pics.

I am 100% positive that this coin does not show orange peel texture. This coin has definitely had acid or some other corrosive put on it. The texture may not have got to the sides of the coin because the coin was probably laid flat and the rims actually held the acid .
Of course, none of us were there when this coin was damaged, so this is all educated guesses. After 53 years of looking at coins, I have seen more than my fair share of acid etched coins.

I believe you now my friend. Thank you. In your previous reply you said "it looks like..." which kinda sounded like there was some doubt there. I couldn't imagine that anyone would be that good know about the difference between acid etched and an Orange peel texture? I've never even heard of an Orange peel texture before this coin. Bob you never cease to amaze me. I'm sorry for being such a pain in the ***. On a better note I did research a possible way it could of happened at the mint prior to posting it which was based on something you said in one of my previous posts which was that you would have to know a way for whatever issue the coin has to of happened in the minting process or something to that effect; so before I posted the coin I researched if there was any way this finish could of happened at the mint and you have to admit that Orange peel texture although wrong isn't that far off to the untrained eye. I learned about orange peel texture; and now I know what Orange peel texture isn't! That's progress right? I'm afraid this may continue on until I get better at this Bob, I hope my next items are less confusing to me so you don't decide I'm beyond all hope.
Thank you my friend.

You will notice that almost all of my replies usually say that the anomaly 'looks like' or 'appears to be'. I do that intentionally. Since I do not have the coin in front of me, I can never be 100% positive. On the other hand, a doubled die, or MD, or any number of other things that can be verified with the photos, markers or other diagnostics will usually get a '100% positive' or 'I am sure' comment.
I am also very pleased that you are indeed beginning to 'get it' (for lack of a better term). Remembering what I had said previously about the process and doing the research to validate what it might be are as important to analysis and attribution as anything in the hobby. Of course I thank you very much for the kind comments.
One more thing for future reference on 'orange peel', and that is that orange peel will never eat into the coin like this one does. Orange peel sits on the surface and could be the result of worn dies among other things. There is a lot of info on the orange peel affect on the Internet.

I agree, this coin was submerge in something corrosive.
