Just a guess, maybe die abrasions or planchet problem. I have quite a few in the same two doors but mine look more like feeder finger scrapes.
Yikes! Maybe have to hear from some others but I don't see how it would be feeder fingers scrapes since it is mostly just on the doors. Maybe a greasy die?
Sorry, I did not mean to say they (are) feeder finger scrapes on mine, they just look similar to feeder scrapes. I have not quite figured it out yet but leaning towards a planchet defect. I have another anomaly with the Ellis Island issue. There is a perfectly horizontal line, raised, in front of the chest of the male immigrant. Have not figured that one out yet either.
Thanks guys... searching around this morning and believe it is a planchet error. Here is the link on error-ref.com I found. Scraped-in Debris
