1992 D Penny (plated/off metal)?

I found this penny in a horde that my mother in law allowed me to hunt through. For the life of me I can't seem to figure out what is going on here with it. I have taken the best detailed photos I can with the weight (2.63g). Google searches came up a bit confusing - Some say off-metal, some say science experiment. One thing I did notice (which shows in the pics) is that there seems to be an impression within the coin of a smaller diameter. It is very shiny and I see no signs of another metal exposed. Can anybody shed some light on this for me?

So is there any value on this with the damage?looks like missing plating to me. need someone from error coin land to chime in to be sure, but yeah it has value
zinc corrodes destructively. steel corrodes destructively. it forms rust and the rust falls off leaving a mess underneath. zinc corrosion is black and it happens faster than rust.
there are cardboard 2x2 with mylar to see through. if you live near a coin store, definitely get one for this and staple it in. be very careful with that stapler!

Saw your message – as others have said above, it’s been plated, in my opinion also.

Looks like it's missing the copper plating.
That is what I thought at first, but some pics of the zinc core look much more dull than this. This finish has a lot of shine and luster. And why the circular impression?
It's just roller damage
All comments reflect the opinion of the author, even when irrefutably accurate.
So is there any value on this with the damage?
Looks like circs are selling for around $80 certified so yours would be less. Seems like a good find though.
How would I get somebody from "error coin land" to chime in? Is there a direct forum for them? Also if its missing the copper plating why does it weigh more than it should?
@FredWeinberg is the expert.
they haunt here but have retired or their own businesses to run. hopefully they stop in
as for the weight, good question. i can say it is within the mint's weight tolerances for the coin
Your coin is not missing the copper plating, this is a damaged coin that was then plated sometime after it left the mint. That is why it is over weight. A novelty item worth 1 cent.

I sent a message to Fred and asked him for his thoughts...let's see if he is awake
This is exactly what I thought because of the weight. If it was missing the plating it should be underweight at least.Hm
Plating is microscopically thin. The weight of the plating is far less than the weight tolerances of normal production.
It might show underweight but not by very much, as was written the copper platting is very thin and doesn't weigh very much. But this is not what the zinc core looks like, depending on what this was plated with it might have some reaction to a magnet.

aw
sorry
I did reply, but I have no idea how my reply and later timestamp was posted before your question to me shows above.
That's because the OP marked your post as an "accepted" answer, so it was moved to the top.
You would think that I would know that by now……
