2023 P Lincoln Cent With Nice Feeder Finger Die Scrapes . Or?

I think Pete is a member here on CCF.
They do not look like any trail die I have seen.
I would have said FFD,but now that you, -makecents- say you read that FFD does not happen anymore makes me wonder
The "scrapes" do look thin and close together so now I am thinking polish lines of some kind for some reason.

No,it was done to the die.

Your reasoning was in the right direction. Post-Mint damage to the coin usually happens to the highest elements on the coin first. Damage to the die usually appears on the lowest coin elements first (because the lowest coin elements are the highest features on the die surface). This is why die surface events like feeder finger scrapes and die clashes appear to be behind the highest elements on the struck coin.

Not seeing any below the banner. There are some roller lines and lite scratches.



The thread by Pete Apple stated "... and Dial Feeder (1836 to 1864 and 1895 to present) ...", so it seems they are still in use. I would tend to go with Pete Apple's research and comments.
(I thought I read somewhere they weren't used anymore. Maybe a statement Silviosi?)




(Hopefully I don't send the discussion off course with my observations.)
I agree with your assessment overall.

On modern cents, I was remembering FF die scrapes going NW-SE, being wide-ish, and smooth like the ones in the cuds-on-coins link.

Here's a thread by Coop with great images, showing the Feeder Finger Damage going in both directions on Memorial cents and the same direction as mine on Shield cents.

I'm thinking out loud here, but it seems to me that the angle of the "lines" is too consistent to be anything other than Feeder fingers.
Polishing by hand (either holding the die to the tool or the tool to the die) might produce "scrapes" on the die surface, but the direction of the scrapes would be more random.
It seems feeder fingers would be more consistent and follow the same mechanical motion over and over and in the same direction.
It also seems feeder fingers could create the damage at any Die State, whereas polishing would only affect older die state dies that were being serviced and maintained.

Good discussion and thanks to all for the input and comments. They keep the brain engaged and thinking.

That's my understanding about Trail dies as well, but....

I'm not in agreement about these lines (or other similar lines) being from polishing. The angle of the lines seems to be too consistent. The width of the lines could be explained by the "sharpness" of the edge of the feeder finger metal as it scrapes across the die face or metal debris from the die that may build up along the leading edge of the feeder finger.



I don't think the die polishing equipment uses brushes, does it?


I believe he was relying on my statement about them not being used anymore, but I found comments by Pete Apple saying they are used, "... 1895 to present".
BTW- I agree they don't look like any trail dies as I've come to understand them.

John1, thanks for this reply "No, it was done to the die."



That's the consistency I'm referring to as to why I'm leaning towards Feeder Finger scrapes causing these lines and not polishing (it's been shown that polishing does cause Trail dies)



Thanks for pointing that out. I was hoping my images were good enough for others to see the area at the base of ERICA.
(I've got to scoot but will come back later this weekend on this.)

Thanks again every one.

That Mint page shows a proof die getting polished parallel to the die surface with a rotary tool.

Planchets and newly-ejected coins are still cradled by a pair of feeder fingers. Eight or so rectangular or T-shaped feeder/ejectors are arranged in a circle to form a dial feeder. You may be confusing reciprocating feeders with rotating feeders. Both employ "fingers" to move the planchets into and out of position. The OP's coin does appear to show feeder scrapes. But I can't entirely rule out unidirectional accidental die scrapes from another source.
