No copper coating maybe???

Found this coin tonight and ironically its also a 1982 but its a small date D from what I can tell. What happened here guys... I dont have a clue.

Copper plating Looks to be removed by a caustic substance (Acid of some kind)
The dull color and pitted appearance is the giveaway.

What about this one its front and back?

This one seems to be toning from being on the end of a "shotgun" style coin roll.
The center portion is exposed to oxygen and sunlight but the perimeter is protected by the part of the rim that is rolled over.
The bumpy texture on the surface is "Orange Peel" and plating blisters.

If you are saying the reverse has the same "bulls eye" toning, then I'm drawing a blank why rev and obv would look the same.

Sort of the same

Found those 2 tonight plus 1 that i can only read 198, is there anyway to tell what year it might be cause its on a copper plachet... Its worn down and weighs 2.97g.

I've been saying for a long time that some natural reaction can remove plating, on my walks here I pick up many cents and often find ones with no plating, mostly in hot sunny dry sandy areas. Some are slightly big and some dished. I know people say the "Texas" cents (supposedly pounded between leather until bigger with no plating) are man made but I think it's not always true. We also had the one guy posting that he dug several stripped cents out of his garden.

The first one posted looks stripped off. One clue is 82 was a big year for stripping them, the first year of zinc so maybe the science class or someone else messed with them.
The second one is tougher but I think also stripped but not sure.

Here's another 82-D

I would still think it is from environmental damage of some kind because the "orange peel" blistering is still under the discoloration.

This the one i cant guess the date on?

Is the reverse just as weak?

I wish it was a 83 to 89 cause its copper platchet lol but i dont see how to tell the date

[Petespockets55]

With that much weakness and circulation wear I would have to say PSD.

[Dearing]

Psd? If it was 80 or 81 or 82 then ots suppose to be copper, wish I knew lol

Post Strike Damage.

That one is copper. That much wear would definitely show zinc if it were plated.
