Sorry, no prizes 
I am going to be posting micrographs of anything that can be found on coins. Some will be easy and some will not. The correct answer is whatever I say it is 
but feel free to disagree (giving your reason) so all of us can discuss it. Images will be posted in this thread at my discretion - several each week. I will usually post the answers late the next day after the quiz was posted.
In order to make this FUN for beginners. I'll ask the "experts" to PLEASE not guess what any of the images are until the next day. Otherwise, folks like (fill in the blank) will get all of them immediately - That's NO FUN. If no correct answer is given by the next day, the "experts" should PLEASE respond. The answer for each image will usually be posted in the afternoon when I add another image.
The Rules:
1.Anyone can guess. That's because even an incorrect guess can open further discussion as to why it is incorrect.
2.The BEST guess is in two parts:
A. What characteristic the image shows.
B. What did you see in the image that led to your guess.
The Question: What the heck is this?

Maybe a spot of tack welding (and contact was too long and started melt/bead the coin) to make into some type of jewelry.
That was my first thought. Loop removed. Ex-jewelry piece.

Jewelry mounting is my thought as well.
It appears to be exuded clad material from the planchet - cracked collar? Created a low spot when struck, hence the missing rim at that location. It's an error piece.
I would go with collar die break as well
Same thought, broken/chipped collar?

Very nice explanation.
Almost like a CUD on the rim!
Interesting for sure. I've never seen this before.

I agree with the above collar break diagnosis. The weakness on the edges of rim where the edge did no strike up seem to indicate a break on the collar and not jewelry.

Here is one on a Lincoln cent:
I am trying to picture the collar. Are they not fairly thick? It would take alot of force to crack it.
As I think about metal fatigue can be a factor in collar cracking.
