Could be wrong, but I'd guess it to be post strike damage. The letters of STATES are still visible in the area in question. If it was a strike through - I doubt they would be.
Yes!! A very nice strike through error. There is no damage on the obverse of the coin that would indicate post mint damage. Thanks for sharing
No damage to the front is increadibly easy to replicate. Using a pair of vice grips, a screw, and a piece of wood. The vice grips would imprint the screw into the revese of the coin, the wood would protect the obverse from damage. The answer is in what GD pointed out. If this was a true strike through error, there would be NO way details would appear under the object in question.
This is not post-mint damage. I believe it's more likely that there was an occluded gas pocket in the planchet which fell out prior to being struck. If this was post-mint damage, the lettering would have been obliterated within the recess, which is not the case here. The lettering in STATES is full but weak.
It looks very similar to this error. http://cointalk.org/thread10316-any-ideas-on-the-3-cent-piece.html
I got my terminology wrong!! I think it should be lamination instead of struck through..... Lamination errors show the details of the coin underneath the lamination. Sorry about that......here's a pic of my Morgan from 921, you can still see the 1, but very faintly...
It's either a lamination error or a strike-through error (struck through a lamination flake). Only close inspection could discriminate between these two possibilities.
Not true, whether or not details show under a strikethrough depends on the thickness and mallability of the item being struck through. The depth, and there for the thickness of the struck through item, on the coin in question is rather shallow. If this was struck through a flake of metal (a lamination) that had fallen from another planchet it is very believable that the underlying details would still show. If you find a clad coin that has had a clad layer fall off after striking, you will find that you can still see the details of the design in the copper core. (although they will be weaker.) It is the same with a thin strikethrough.
True, and thanks for the added info (always glad to learn more). To me, the indentation looked like the shape of a rounded head screw. If that were the case, aside (I'm guessing) from damaging the die, I'd assume there would be no details beneith it. Question to all. Is it me, or does the back of Lincoln's head have straight lines that should not be there? Just curious.
Those lines appear to be scratches on the coin, it has been circulated after all. They do not line up with the indentation on the other side.
I am almost certain that it is a "Struck Through Lamination" error! I have many of them, some with the lamination piece still attached and some without the lamination piece still attached. If I still had one of the best that I ever found,I would post a picture of it. However, I sold it over 6 months ago! It was Struck Through Lamination on the Reverse and the lamination piece which had long since been dislodged, was about a 1/4 inch wide and extended from rim to rim. The Lettering and Wheat Stalks inside the Strike Through Error, were still strong and highly visible! Frank
