It REALLY does look like a 7 is running across an 8. It didn’t have to be removed before the 1958. It could have been remaining after being died OVER a 1958. IN is doubled. Liberty I is doubled. Lincoln die clash “neck back” on the reverse.
Everything you are seeing is a common occurrence. There does seem to be a clash. But nothing significant to give it a premium. That's the reason you see the heavy polishing lines on the Obv.
Let me guess. You have no hobbies and few people to interact with. So you are here with this. Advice. This is not winning you any friends on here and each time you post things like this that are not things in reality, less people want to interact with you. But feel free to not care that I said that. We like good pics, and you have them. But we also like when errors are errors and not made-up nonsensical things, with stories that don't compute, to boot. I come looking for good pics and to see if you are still in your old rut or if you are finally getting serious and have an actual error worth looking at. So far I'm zero for (insert whatever number is applicable for the numerous posts of yours I've looked at). P.S. Although coins can be road-kill, they never can actually be dead.
This was meant in correspondence to how even though a 1958/7 was debunked as a class 7 modified hub doubled die....(John Wexler) excitement still built to realize there was still that upper corner which obviously still retained as something that could be spread onto every other coin as only something with actual die implications could.... to see what looks like an uneven seating doubling with the last chance explanation of an actual possible 7 leaving a corner imprint.... LOOK UP MINT MARKS ON THE US MINT PAGE AND IT WILL TELL YOU UP TO WHAT YEAR PHILADELPHIA PLACED DENVER MINT MARKS BEFORE SHIPPING TO DENVER, AND AT WHAT TIME DENVER TOOK OVER PLACING THEY’RE OWN MINT MARKS.
You described a reverse die clash from Lincoln's neck and showed a closeup of it. That is not a die clash. It's a die crack! Very common on coins, especially Cents. There is no doubling. As explained before, one letter here and there is not a doubled die. Get it together!!
The back upper point of the Seven could have left a lasting impression in the die if indeed it had tilted in that direction, lifting up IN and pulling Liberty-I in that direction with it.
Now Kasia , do not be a speciest, although it is not yet banned in the rules, it hurts the feeling of their masters.
OK,.... NO, your logic is in the wrong direction. Look at this photo from the Lincoln Cent Resource site. The 7 marks would be below the 8, not on top. Yours is just damage. Jim Jim
