Sorry, but it looks like just a discoloration on the coin making it look like it's close. Take your photo from as close to directly over the coin as well, and not from an angle. That will help to see the distance more easily. edit: I just blew up your own photo #4. You can do this also to get a better idea on coins that you question:
The other marker for a CAM is that the designer's initials FG would be further away from the memorial and not have a serif on the G. Sorry, but this is a regular '92.
Something between the A and M makes it appear to be a CAM, but it's not. Keep looking and good luck. Welcome to CT BTW.
If you've found one and don't like it, i'll give you 1 $ for it, plus shipping The 1992 D close AM scores pretty big, though this ain't it. If I found one, I'd be quite surprised and happy. This one was just an MS64. https://www.coinworld.com/news/precious-metals/rare-1992-d-close-am-cent-realizes-20-700.html Another very good article on it 5 years later. https://www.numismaticnews.net/article/second-92-d-close-die-pair-found Chris, there were 79 known graded examples at the printing of the above article. You do acknowledge that this is somewhat rare, too?
I do not think anyone has found any such here recently or we would have all heard about it. Without the wink , I would have considered it an offer and have to delete it. So lets be happy for what each of us really has in life. Jim
This was a good find not too far back, though it wasn't a Denver mint. https://www.cointalk.com/threads/is-this-a-1992-close-a-m-lincoln-cent.337698/#post-3495994
I have to agree this is not a CAM. As stated the AM is to far apart the FG is to close to the memorial. Also you can clearly see the A in states is centered between the T. This also makes it a WAM.
