I found this a few weeks back and figured i would share it here as well. It is a 1940 P Lincoln that had some copper scrap struck into it. Three pieces were retained over the years through some miracle, but two have fallen out. I thought originally that it was a lam error, but was corrected by the experts.
regardless off what the experts told you this is a common lamination on your coin. if this was scrap struck onto your coin if would have a shallow sunken in line going all the way around the struck in metal. look above the E in LIBERTY and you can easily see that this lamination piece is still solidly attached to the rest of the copper cent. the wheat back cents are extremely bad for being struck on defective planchets.
for someone that is so wrong, you sure are sure of yourself. there were 5 separate pieces of scrap struck into the coin at minting. the one on his shoulder, along with the piece at 6:30 have fallen out, leaving the "struck through" areas you see. the other three pieces are retained. I am not asking opinions. I know what it is.
Hey! I told you the truth . anyway this coin is not worth anyone quarreling over . just because two of the pieces have come lose and fallen off the coin does not make it a struck thru scrap coin. laminated planchet coins also do this. If you have quite a few of the wheat back cents you will find lots of these laminated planchet coins. you need to remember that all struck thru scrap pieces will not be solidly attached to the coin at all. I have collected error coins for about 50 years so I do know a little about errors and varietys.
Ok I looked at it again and it still remains the same. It don't take a expert to see this is a laminated planchet coin. the area above the E in liberty shows that the big area at the back of the head is still solidly attached in the back part of it and was part of the original planchet. if this was a struck thru scrap area there would be a sunken in line going all the way around this area. struck thru foreign metal scrap pieces can not attach solidly to a planchet . as can be seen in the photo the big area looks to be unattached behind Lincoln's head and raised up a little , if this piece was totally unattached on the other end like a struck thru would have been it would be fell out and gone. this one is a simple one to identify . hopefully someone can learn a little from this thread. EDIT: The area on the rim below Lincoln is PMD
To start with, had you taken the time to look at the pictures at Lincolncentresource, you would have seen that the area above the E is NOT attached. And then just how many laminations have you seen with a rolled surface beneath the laminate?
I did take time to look at all the images on Lincolncentresource and the area above the E in liberty IS attached on the left hand side and the other laminated areas IS partly attached also. good grief
You can pound two pieces of copper together all day, and if the connection point is not on the verge of melting, it will not fuse together. My guess is it's an amazing lamination error.
The closest you can come to "fusing" metal together without using heat is a crimping or knurling process, and even then the seam is still visible by eye. This is a close up pic of a 3/4" diameter coin and I see no seam line above LIBERTY
This is a lamination error, although I can't rule out the possibility that a detached flake was struck into the coin.
