It looks like someone tried to dissolve the copper with acid, leaving a nickel shell. I'm not sure if that's even possible though, can you see how deep it goes?

It looks like a foreign object that was present before the strike. Most likely it was squeezed into the edge of the blank as the latter passed through the upset mill. A very rare occurrence. The object looks like it's very hard and resistant to wear. If possible, I'd like to inspect it up close and perhaps write it up for Coin World. Error coin writer and researcher.

That's very interesting, I've never heard of something like that happening, do you have an idea of what kind of object could get into the die like that?

If my speculation is correct, the object didn't enter the striking chamber. It arrived embedded in the planchet. So it makes no sense to ask, "what kind of object could get into the die like that". Identifying the origin of small embedded bits of metal is next to impossible in any context.

Have you checked the inclusion with a magnet yet?

Thanks for the replies, everyone. I just tried checking the piece with a magnet and it does stick. That explanation make sense, just never heard of an error like this. Exciting stuff!

The fact that the inclusion is iron or steel makes it a much more interesting error than if it was just a hunk of copper or nickel alloy.

half n a half, I showed your photos to my husband ( a design engineer) and asked him to show the engineers and tool and die makers that he works with.
What I find most curious is what appears to be the space around the foreign object.
My questions: is it possible to move that object? And, is that really empty space I see or is that a shadow?
I don't know that we'll ever have an answer to this mystery but we're having a lot of fun trying to figure it out.

It has been sent off to mikediamond, but the piece is definitely stuck and not movable. If I remember correctly there is a slight space on some side, but I'm not positive. Hopefully we'll have some answers from mike in a little bit.
