... I don't believe that a little piece of steel in the planchet could do any damage to the die ... The little piece of steel can be small enough to fit inside the planchet, and still be far larger than the thinnest part of the finished coin. Consider the pressure generated in the die-bangs-die scenario. Consider the pressure used to impress the die into the planchet. In which situation is the die more likely to suffer damage?

These keep showing up! There are too many of them with such similarities for them to be the result of random events! There must be an explanation for what causes them!  Random events include dies accidentally being dropped on each other, an engraving tool accidentally slipping, a polishing disc accidentally touching the edge, and others I have not thought of or have not yet been suggested. |

Maybe they are left overs from a die abrasion that didn't quite get polished away. Take a look at the coin on this thread: http://goccf.com/t/278355Now imaging poling those lines out and missing a small area next to the rim. Wouldn't that look similar to what we are seeing on all of these other cents? |

On that thread, the poster shows a 1994 Lincoln Cent. I found a 1994 Lincoln Cent that has marks similar to what we have been seeing on other cents, here is a photo of the coin I found.  On my coin you can see the line by the second T in STATES and also to the right side of the T in CENT. I attempted to do an overlay of my coin with the 1994 that shows die abrasion marks to see if the lines matched. They are remarkably close, but I don't think the photos of the other coin are shot straight on at a 90° angle with the coin, so making an overlay exact is difficult. I do think we should try to see if we can match these lines up and if they will line up, that would solve the mystery. |

Thanks, Claude - this could have possibilities - at least for some of them. The exceptions might be those marks which are similar in appearance: a wider base near the rim and tapering to a very fine point (or double point). There could be 2 different etiologies here.

In order to polish these away on the die would require the removal of all the field in that area. If they do this it would are to remove more field the devices would be altered.  The devices would be tapered. It would probably take a lot of time to remove this much of the field. But the damage is to the die, that is why it is raised on the coins. Struck through wire would leave an incuse mark on the coin:  When I bought this coin, it was told to me that the wire was on the coin. The finder touched the wire and it fell off. I didn't know whether to believe that or not. But after a few year later, his fingerprint showed up on the coin. Then I believed that story. |

Thank you for posting the extra photos. There is too much reflection on the area of your coin that I need to see. Here is the area we are concentrating on.  If you could get a a close up of that area without so much glare, it should be what we need. Edited by cwb

The angle of the photographs of the coins is not the same on each one, which is making it difficult to get a 100% match.
The lines on each coin are parallel to each other which leads me to believe that what ever made the marks on the die was at the exact same angle with the die's surface.
I think they are from the same die at different states, one before the abrasion marks were removed.
Maybe someone else with some photo software can make a comparison and give us another opinion of whether or not they think they match.

I see these are listed on e-bay now being described as broken die errors.
Thanks for pointing this out! It does look like the same die, but perhaps not the same die pair. The heavy scratches around liberty seem to be absent on the ebay example. (No progress, by the way, on my trying to look into this phenomenon further). |
