I wonder if it could be a mark from a roller?

Seems like a straight line impression. So I can visualize a roller impression seems most likely than a rolled through something foreign, but I wasn't there so I'm speculating as to which. Thanks, Doug.

So, since EURI & S UN are both affected, this would be bilateral accidental abrasion?

I think that being a feeder issue is more interesting a possibility than what I was thinking might be a planchet issue. What I was thinking did not account for the weakness of EURI & S UN.
Thanks for the reference!

Pete2226, this got me looking deeper as well for feeder finger issues around this year and or prior to. All point to veridical movement across the dies unlike later years scraping diagonally. Thanks, Doug. https://goccf.com/t/119754&SearchTe...eeder,finger |

Pete: I had to alter your image a bit. But it looks OK now.

Thanks - I suppose if I really wanted to illustrate Mike's point I should have a close up of EPLU and S UN.......

No this was fine. It just was missing the area between the two images. So I added parts of your image in to fill what was missing.

It seems to me that the "story" in Mike Diamond's article on accidental abrasion is the effect it has on reducing LURI - and for my coin, also S UN. If I understand his point correctly, I would title my coin as BILATERAL FEEDER FINGER ABRASION. I know that the feeder finger reference is not yet authenticated. His reference to a right triangle is to the entire area which includes LURI and the "trench" which appears vertically on the coin. The right triangle is less visible on my coin than on his example. Here is the link to what he said that I am referencing, along with a quote: http://www.error-ref.com/?s=acciden...043;abrasionQuote:
The reverse face of this 1944 cent shows an area of accidental die abrasion that approximates the shape of a right triangle. Enough metal was removed from the die face to create a distinct rise on the coin's surface which almost swallows up the letters LURI of PLURIBUS. Die damage of this type — both unilateral and bilateral — occurs in the same area in Lincoln cents that date from 1917 to 1945. The repetitive nature and consistent appearance of the damage strongly indicates a machine part is responsible. While a feeder is a likely candidate, the theory has yet to be proven. Damage in this area can take the form of abrasion, a die dent, or a combination of both types of errors. Here are some photos which may be compared to his example photo:   |
