🔎 UNIDENTIFIED I think I have a copper dime error? I found it in a box of coins belonging to my dad, and this dime seems to look similar to other examples online.

(I tried help on reddit and the 2 that responded are idiot jerks who don’t know what a copper dime is). Copper dimes are errors that were minted on copper penny planchets accidentally. The condition is not great but the date is 1986-p

It could be another type of error that caused the nickel clad layers to have fallen off or a lamination error but I have no idea. I have never come across one but I do know of them.

Also the whiteness is crap stuck to the coin and the light glare from my phone camera. The entire coin is a dark copper color.

I believe what you have there is a corroded environmentally damaged dime. A cent planchet won't fit in a dime coining chamber so that can't happen. A coin can be struck on a wrong smaller planchet, but not a larger one if the collar is in place. The collar strikes the reeding on the edge, so it was in place on this coin.

While it should be pretty much impossible to strike a dime on a penny planchet, it apparently has happened. But I don't think that's what you have. I think it's just an ordinary dime that has been damaged so that the clad layer is missing.

Here's what it looks like when a dime is struck on a penny planchet. It doesn't look at all like your coin.

Correct, that one was struck without a collar which is possible, the dime collar makes it impossible for a larger planchet to fit.

I agree with environmental damage. Not an error coin

Agreed.
