Nice picture! Thats what I think...lol Did you make it black and white to get a emotional reaction from the viewer?
If I had to guess...(and this is pure speculation)...I would say heavy die scratches that just happen to almost look circular. If you look closely all the lines are straight...
Happy hunting

If you read the description it talks about "atypical die polishing"

Given how common heavy die polishing lines are on cents of that era, I'd lean toward that diagnosis.

Lathe lines are evenly spaced and really easy to identify once you've had one in hand...I agree with the polishing.

I have to agree with the die polishing comment. Lathe lines always have a "bullseye" look to them.

Thanks all, I now believe they are not lathe lines. Can anyone explain how these marks got there? This is the first one I have seen like this, thanks. John1 |

But when the mint abrades a die isn't it a random process? The polishing lines are all over the place while the lines on my coin look deliberate. Just trying to understand what happened to my coin. Thanks all, John1 |

This is just a guess but think of a small die grinder with a small cup style rotating wire wheel brush. That would leave radial lines like this rotating around the centerpoint of the die grinder. To me it looks like something similar to this.

But if you look at where the base of Lincoln was you will see lines that are straight like an octagon would look instead of circular like a wire wheel would produce. John1 |

With the wires going in and out of the low areas in the die that form the pilars they will change direction and not travel in a perfect circular motion. Keep in mind this is still a guess and not an answer.

I like pyrbob's guess, and that's as good as it gets. Give a man a tool and he'll do whatever he feels like to get the job done so I'm not sure you can ever get a definite answer.
