2001-P Cent With Crazy Strange Lines.

@ Pete this coin it is 2001, so the used the Horizontal presses which do not has FFs.

The HGK3 explanation is very good and could not be resumed only to FF and expand to any relative hard material which the Die struck on.

In my vision for this coin the lines on the coin, mean the pattern and the surface of the coin present them, made me think this Die has those marks from the times start with Squeezing and ended with the installation. I go more after squeeze when the Die go to the rework of the outside form and hardener.

I will put here photo of Feeder Finger in pair, because those work rotative as a dial phone. One took the planchet and install on the place and the second contrary rotation of the first one took out the struck coin.

So I will show here the FF of the last Gräbener vertical press use for BS in Denver and also a Gräbener press photo.

Thanks and give your feedback.

I'll admit, I don't know the intricacies of the presses used during this era of Lincoln cents, so I'll take your word that the feeder fingers in the images above were no longer used. However, something regularly scrapes the dies, either during the insertion into the striking chamber, or during ejection. The scrapes are almost always similar in appearance, and normally run in an approximate 45 degree angle NW/SE. If memory serves me correctly, most if not all I have seen like this were on the reverse of this era cents. Something that moves in the same direction all the time is scraping the dies. I ran into this 1999 last week searching bank rolls.

Hope you don't mind the images and hope they work. Haven't uploaded in a couple years.

Sil, I just don't know. You said the mint didn't abrade/polish dies after the early 2000's too, just don't know....

The only abraded (polishing) Die on this days and today will be after the squeeze and after they made the Die before to be hardened. then after is no more intervention, just change. That abrading it is a very short period on cotton buffers.

Make: the coin you referee show inconstances in the lines and show as like scratches and not polishing lines.

We have in the coin history periods of technology:
1. 1778 to 1909 (1910)
2. 1910 to 1965
3. 1966 to 1999
4. 2000 to present

So do we have to mixt all because reticence or other reasons? No, just adapt.

PS: Better tell me about the fir of my photos with the lines. for you: they fit perfect.

Also please do not confouns some times the bancs lines.
