Sorry. @CoinRoller. These members are great. You jumped the wrong two members. No flies on these guys
Since you marked out areas of interest, I will try to address them so you can see why the other members were able to respond so quickly. At top left the C has a contact mark. You can tell a hit happened because the metal has to go somewhere. You will see a ridge in one direction where the impact pushed it. The upper E shows another contact mark. Just to the right is a ragged groove. This is generally a flaw in the planchet. These are irregularities from forming and rolling the metal sheet from which the planchet is punched, or from banging around in the drying tumbler with other blanks. This simply was too prominent to be eradicated by striking by the dies. The lower E was hit by the edge of another coin, perhaps as they flew down the chute after striking or during bagging. You can see it has a distinct curvature and you can easily imagine holding another cent up to the mark and fitting it in perfectly. Even with less than perfect focus and resolution on your images, these are features that these experienced commentators could identify at a glance. Here’s another example. You can find a few dings, some planchet irregularities, and also some bright lines that are marks made on the die by polishing, then transferred onto the coin.
