What Happened On These Two Coins

Not a sharp, pointy tool like a box cutter or X-Acto knife. That argument goes equally for struck through a wire or similar object. A struck through should not result in raised edges. mrh70's experiment is a great tool. Put up a hypothesis, test it, and examine the results. A box knife produces results much like the coins shown. Doesn't mean that it had to be a box knife, but it does mean that it can't be ruled out without more information. By the way, don't use a box knife to get coins out of those plastic bubbles that the mint uses on uncirculated sets (see above examples of what can happen if you mess up, which if you are me, happens almost every time).

I confess my default guess is always PMD, but I don't know.

Ok, it seems like the poll has scrolled on the one day page. Here are the results.

ANSWERS:
Post mint damage [16%] 9 votes
Coin was still in mint cello. Not damaged. Not re-sealed. If the coin was damaged almost impossible to find something that small (Except for wire) to make this mark. The reverse was totally normal, so it wasn't damaged.
Rim bur damage [4%] 2 votes
This is also a strike though error, but with a larger piece of material making a mark which would have been too large to make these marks.
Struck through error [55%] 31 votes
Correct answer. Struck through wire.
Parking lot coin [0%] 0 votes
Still in wrapper. Not typical damage. No one voted. YEA!
Damaged in a garage [2%] 1 votes
Whay would make a mark this small and not affect the reverse.
Cut with a box knife [16%] 9 votes
The plating would have been removed if this happened. It would look like this:

Not a trick question.... this time....

Not to dis-hearten anyone, just education. You never know what you will find out there? A lot of correct answers. NICE!
Thanks guys. Ready for another one?

Me too! I thought it looked like wire.

Thanks coop! I really enjoy these. I hope you keep them coming!

The one thing that made me say knife (which does not have to go through the plating) was the tapering ends. I guess if the wire pieces were formed by pulling instead of cutting, this is perfectly natural. Just for fun, here are a couple more struck throughs, one grease (you can just see that some of it was in the serif on the T) and the other lint (which is still embedded in the coin). Both are 2009 Lincoln dollar reverses, one proof and one uncirculated.

The marks on the second image appear to be thread. Unlike wire, they curl in many directions.

Exactly!

Although I did get this one right.

Thanks for the quiz, Coop!

Be this would have had more incorrect answers if Die Crack was an option. Good stuff.
