A very difficult quiz for the weekend. What caused this characteristic?

You'll post pictures of the ship?

I voted it is a scratch but the new image looks like a fiber/lint just laying on the coin.

 

A bi-level die crack

 

Another spammer broke through the wall.....

 

Something from nothing leaves nothing. Full pictures would gather a better response. Thanks

 

I thought scratch, and that is how I voted. After the second picture, I am going with die crack.

 

Looks like a die scratch/gouge to me. Just does not seem to be as sharp as I would expect if it were a die crack. I would also expect that somewhere out there are many more that look like this.

 

I’ll post some photos when I get back next week. They’re all on my camera and the bad WiFi I’ve had at hotels won’t let my phone connect to my camera.

I’ve seen a ton of cool things I’m gonna share.

 

My first thought based on the light was lamination.

I think it's too smooth (not jagged) to be a die crack.

Then I thought PMD, but because of the area highlighted below, I think that can be ruled out. There is a crater that looks like a hit, but the line goes through the assumed crater, pretty much uninterrupted.

And that leads me back to a lamination, or a flawed planchet, so that's what I'm going to guess. I'm probably wrong.

 

That's what I thought I was seeing in the photo -- a bright line indicating a raised edge, but no dark line indicating a corresponding drop on the other side. This would lead me to suspect a broken die, but I'd expect to see more signs around the break, and I'd expect it to go edge to edge. So... lamination, or similar planchet flaw, that raised after striking?

 

The irregularity looks to be a continuous raised area going up at a sharp angle to the right, across to the left, and then down in a less dramatic fashion. Taken overall, it appears to be a smear of metal on the original planchette, and with the light coming from the right, raised above the body.

 

This is what I see a thread/fiber laying on the coin.

 

Dear Mr.Q and anyone else...

Please try to incorporate this THIS BEST ANSWER into your thinking from now on:

Full pictures of a coin are NEVER NECESSARY to be able to see most microscopic thru tiny to small characteristic features on a coin that do not involve its edge, rim, or opposite side - EVER! So please quit asking for them because it shows that you may not be paying attention.

New Info. The surface is bi-level and the mark DOES NOT break the coin's original surface. I don't recall ever seeing this characteristic in the middle of a genuine coin before.

@JCro57 With the description above, I'm 100% sure an error expert of your caliber knows the answer. Please explain what this is and how it happens for the members as I'm going to be away from a computer until tomorrow. Thanks in advance.

Thanks in advance for taking over for me in this thread!

 

Lamination over a fiber?
I like these puzzles even if my success rate is really low.

 

Some of my thoughts on images.
If you are buying, selling, teaching or asking for opinions, out of focus microscopic images just seem to create problems. There are scopes out there that get past this. Just a bit of study and practice.
There are good reasons that folks ask for full size quality images of the coin. Many scopes have a hard time taking full size images that are still in good focus. It's all about the camera and the time a person puts into learning how to use it. Folks on a PC or even phones can enlarge the image and have a better understanding of the coin but it really needs to be in focus when it gets posted.
I'm a big fan of using a DSLR with a macro lens. Not hard to learn and they just get the job none.

 

For those who didn't read my post above...I will never post an image of a full coin, its rim, edge, opposite side or the container it came in when in my opinion it is unnecessary and adds nothing but to my post.

 

I've enjoyed many of your threads and replies, but ummm ... how are others supposed to learn from your posts from limited and dark images? It's only taken 35 replies plus your original post to come up with an answer of .... well we haven't yet. Maybe that is the purpose of this exercise. To get people to rely on vocabulary rather than images?

Physicsfan had a very nuanced and detailed description and I was seeing a lot of the same things. But IMHO I believe it to be a die crack based on the die state (Mid to LDS) and the irregular shape of the meandering raised line. (The light source seemed to be about K3.) I say meandering because it is very faint but looks to go up to the top of the dome and south into the letters as well. And the brighter part of the line seems to be on the right side indicating it is a raised line.

Forgive me if I haven't described what I'm seeing very well.
(Are we allowed to use your image or should we use only our vocabulary to describe what we see?)

 

I'm hesitant to bring up the term Die Sinking into the conversation because it's usually limited to very early coin production before the roller presses. I don't even know if that's possible on modern coins.

I'll just say it shares the appearance of coins where the die sinks prior to breaking. But the edge usually has no sharp line until a break occurs. It's more of a dull "bend" in the surface.

 

If it is a die break - there would be many existing struck examples - which doesn't seem to be the case - as no one here has yet identified and attributed it to a specific die. Makes me think it is a unique example of a single specific strike. I'll venture a guess of it being a strike through cloth with a retain thread.
