I think the percentage of die cracks on post-1982 cents is very low due to the softness of the zinc planchets use to produce these coins. The most common place for the reverse of a LMC to develop a die crack is from the corners of the memorial to the edge.
Die cracks are raised. The mark on your coin is recessed, so it can't be a die crack. Think about the minting process. The die that strikes the coin is in relief. All of the high points on the coin are low parts on a die. A die crack in a die will be recessed, so it will leave a RAISED mark on the coin I would strongly suggest you spend some or your roll searching time studying the minting process instead of looking for errors. The more you know about the process, the easier it will be for you to recognize basic damage. You should also buy a copy of "A Guide Book of United States Coins" also called the redbook.
I wish I have time and patient searching and reading but I will try thank you sir! I have another penny what can you say about this?
The first one is damaged as that's a scratch. The second one is a stain. A die crack will be raised. A lamination will be attached or detached but it will be separated from the metal on the coin.
