White 1986 D U.S. Penny

I have a white 1986 D U.S. penny and I was wondering if anybody had any idea of why it isn't the usual copper color. It is the same color as the 1943 zinc wheat pennies.

upload some nice obverse / reverse images here that we might use to add this coin if it is missing.
besides it would help others to help you identify your piece

Here is the pictures. Let me know if they need to be better. Thanks.

hm, interesting. however after doing some little research it might be some kind of fake.
since modern US pennies are made of copper plated zinc it might be that either
1) the very thin copper plating is totally worn off
2) or someone added some "wear" by using physical force or chemicals to dissolve the copper

3) very small chance that the mint "forgot" to give it a copper plating?
maybe someone else can check this, too

Maybe it's still copper-plated.  Don't forget about good ol' corrosion, too.

I think the copper plating is all off of the coin. It feels like a zinc coin and sounds like one when you drop them on a hard surface.

I thought it might be corrosion too - as in perhaps someone with a metal detector dug it up. Hence the patchy discolouration, especially the obverse. I know a while under ground does change a coin's appearance. Though if it sounds like zinc, maybe it is that then ?!

I had a coin expert look at the coin and he said that somebody probably put acid on the coin and it ate the copper off. Thanks everybody for your input!

Unplated cent error coins can be worth good money however I would agree with the expert in that the plating was removed with acid. If this was a plating error then the details would be more fine and smooth as if the die had hammered it that way. Your coin looks way too eroded to be a natural unplated.

Sorry to see the bad news
