I could maybe see a long acid bath, buried idk about that. It has no real dirt or staining from being buried to me. If placed on top of another nickel it almost seems as if it's missing the entire rim all the way around along with being half the thickness. Would acid really take the rim off so evenly without major pitting?
Also along the rim it almost resembles a layered coin idk if acid or dirt would cause that type of look then again I have never given a coin and acid bath.

@MRJ: The acid will not made this thing. If was acid, must be an mild acid which can ate this kind of alloy and hard to be find in nature. Another it is the cyan hydrate of potassium which also no way. Why I say electroplating? because on this procedure you can do in same time cooper plating and nickel plating in the same electro bath. In lab I play with some Canadian coins and I see that first the sides will dispatched the ions and then all the ions come from the center where it is accumulate the most electro-magnetic-energy and the design remain relative OK.

It was damaged by an unknown process - buried or acid treated or electrolysis or something. It is not a naturally occurring coin.

This coin is smaller in all directions (thickness and diameter) I'll go with a controlled acid dip.

Well sadly that takes all curiosity out of it lol. I'll still keep it as an example of a acid damaged coin but it doesn't get a place in the main collection lol. Ty to all for clarifying the non error problem on this one :D

Environmental damage, probably intentional. Lack of rims tell us it's not a mint error. Post mint damage.

Hmm.. Data has a good point, I'll wait to see if the OP can give us more information on this.

Also odd that reminded me of this: A tapered planchet is one that thins out at one pole. Appearing in all denominations, the 1950s produced an unprecedented number of such errors. Weight would be lower but not that low. Tapered planchet errors often co-occur with rolled-thin planchet errors. In other words, all parts of the coin are thinner than normal, not just the taper. The weight isn't exact for a silver dime planchet (2.5g +/- .09g) (2.59vs2.66 this coin) but does have that type of look when struck on a dime or smaller planchet.
