I've been off the board for a bit and have some interesting finds. Here's one. Rich copper color on both sides and edges. I've posted a lot of coins I thought were improperly annealed but the experts said we're PMD. This one is the real deal I believe.

Just posted a similar coin. It seems to be a chemical damaged or buried coin. Apparently common to find during metal detecting.

Your coin looks to match number 1 in the list of Dirty Dozen Damages. Even though there is no premium value to these, you might try to find a nice example of each.

1) discoloration - stains from a beverage, or environmental damage from being buried, heated, etc.
2) scrapes over much of the coin - damage from sliding on pavement, a parking lot coin
3) coin bent or edges not round - it has been smashed with a hammer
4) coin blank on all or most of one side - someone machined the surface away or sanded it down
5) mirrored lettering - a vise job, a coin squeezed against another in a vise
6) rough, pebbly surfaces - a coin eroded by acid, it might now be underweight
7) smooth rims, smaller diameter - was trapped rolling inside a dryer, a " Dryer Coin", or tapped with a spoon
8) clear mounds on coin - glue that has dried transparently
9) small indentations in the shape of the letter D - marks left by the impact of the reeded edge of another coin
10) large blisters - coin exposed to high heat, such as in a campfire
11) shapes, often letters or numbers, not indented or raised - Pareidolia (like animal shapes in a cloud)
12) a circular scrape just inside the rim - " Ring of Death" caused by a coin wrapping or vending machine

Don't despair! Error coins remain ready to find from circulation, but they are outnumbered by unusual looking coins that merely have been damaged. If you can imagine a way to change an undamaged coin into one like you see, that's probably exactly what happened to it. Changes to a coin after it leaves the mint's striking chamber are considered post mint damage, or PMD, and have no premium value.

Since the consensus was that it was PMD, I cleaned it, just a light rinse with warm water for 30 seconds. So now, are you SURE it's not improperly annealed or other mint error?

I'm not too sure it is PMD here. There is a lot of copper showing, with some annealing issues, sometimes the copper will migrate to the surface.
I think that Silvio needs a look at this one. He is a metal composition specialist here.

I'm leaning toward post-strike damage, with a good dose of environmental toning/staining. Just my opinion.

I'm in the PMD/acidic exposure camp.

It appears to be environmental damage, although I think it looks kinda cool. No additional value, but still a fun keeper as an example what can happen to a coin in the wild.

Annealing is a heat treatment process to make the planchets softer for striking.

Four things can go wrong...

* Too hot
* Too cold
* Oxygen in the annealing oven
* Improper quenching

Got it on a scale. 4.81 grams. Does this change anything?

Thank you DEAR. The quantity of the Cu in Nickels it is to low to made such migration with out the EMF interferences to change the ionic stability.

The texture of the coin show clear acidic interferences. I think more to chlorhydric acid at low saturation. I have same results with nickels let one winter in the soil mixt with horse faecalis (very acidic).
