PMD?

This seems strange , is it post mint damage?

Thanks for looking.

Further out shot

That looks like a die crack, which is not PMD, but I will defer to more experienced and knowledgeable members.

Well thanks for taking a look. I have heard of die cracks. I am not a big collector of mint damage or such as that but this caught my eye and was wondering what others thought as I am by no means am an expert. I ran ito this in my daily review of a roll of random pennies . Its odd but I found two other anomalous looking penny.  the very next day. Sometimes I hesitate to post on the forum because feedback is at times shall we say more like brow beating sometimes😄But I want to find out what some anomalies are . I guess some people think your trying to make it into a million dollar find or something. I know that's not the case. Its just finding out and learning stuff that's important.

I have seen other posts here referring to websites that deal specifically with error coins. Maybe you could find one of them and get better info on your anomalous pennies. I doubt you'll become a millionaire, but depending on the error, they will probably be more than a few cents. I don't really look for or concentrate on errors, so I am of little help there. Good luck.

Here's some info on all kind of Lincoln cent errors. Unfortunately, die cracks are missing: https://www.lincolncentresource.com/Errors/Lincoln_Cent_Errors.html

AHA!   Thanks very much for that guidance and gouge.

On your first picture it looks like you can see the zinc. I would not expect to see that with a die crack. 

My understanding of a die crack is that it would cause the planchette to poke up into the crack. It seems there is a ridge there rather than a depression which would be caused by a scratch with a knife or implement. It is also interesting how exact the line is bisecting the right side of the U. I dont fully know the reason of the exposed zinc. Does the copper coating peel away if it is scratched ? It seems that the copper coating would peel away if the planchette was pushed up. I am not entirely sure of the dynamics of bonding of the copper and zinc . Maybe a metallurgist would expound. Maybe you are a metallurgist. 

Closer pic but I wish i could get a lateral view so I could convince myself that it is poking up. It feels like a ridge , but a scratch could well feel the same way I guess. 

Below I have tried scratching a sample coin at that time with different things I cant exactly replicate the subject coin . It seems a scratch of that nature is hard to do other than a straight line , I tried to curve the scratch like the subject coin but that was difficult.

There is my somewhat exhaustive research , and that with no positive determination .

All good questions. Before I first replied I too tried scratching and convinced myself it wasn't a normal scratch. The copper is not bonded but plated on as a very thin layer of pure coper which is very soft and flows easily. I've never seen zinc poke through when the thin edge rim is formed.   I believe because of the size of the coin and the material involved damage to the die other than wear in minimal.  I'm not saying it isn't a die crack but if it is there will be thousands of more similar ones out there. We may have to just wait and see until another one looking almost exactly like yours is reported.

The other thing that makes me question a die crack is that it extends on the rim. A crack on the die wouldn't go that far.
