1982 penny please note the rim shows no signs of "erosion" which I would expect if it was bathed in acid or was a "dryer" coin. there is also so flattening / crimping in various places on the rim, no signs of "claw" marks from vise/pliers/grips "jaws" thoughts? opinions?    thanks wade |

Definitely acidic reaction in my opinion. Anything else that happened to it likely occurred before that.

The cause of the mysterious flat spots?
1982 cents are 12-sided.

This looks like acid attack to me as well. Don't know about the flat spots etc but the general etch has the hallmarks of an acidic environment

I thought these types of coins were called 'deficient plating', according to 'coinsandcanada.com, error webpage.  |

Deficient plating?
There's no plating on them, they are one continuous alloy.

Did you look at the page?
It looks quite a lot like this one.

The deficient plating photo on that site is of a Chromium nickel missing it's chromium plate with the underlying nickel plate intact. The surface of that five cents shows signs of bag marks, dings and such ...
I don't see the similarities at all Shafta, sorry if I'm sounding stubborn, I don't mean to.
Just to reiterate, the coin type in this thread was not plated, it was a single uniform alloy. Subjected to acid in this case I believe.

It could have been dropped on the beach 30 years ago and someone has picked it metal detecting and put it back into circulation.
That would explain the rim damage (banging into rocks ect via wave action).
And the sands abrasiveness along with the alkalinity of the sea water would account for the other damage to this coin.
Just a theory, but it may have happened this way
