The damage is post strike. That area has incuse devices. (Below the fields on the coin) An hit on an incuse area will leave an incuse mark on the coin.
This is just damage to the coin. Happens a lot in circulation. If this were a coin with a premium, it would be considered a cull coin and be a face value coin and remove as much as 90% of the premium value. How can a die make incuse marks on the coins? The die is a negative. What is raised on the coin is sunk into (incuse) the die. So for the die to have raised areas on the coin, they have to have incuse areas on the die. For incuse devices on the coins, the die would have to have raised areas on the die, to make those incuse marks. IF you take a piece of aluminum foil and press it into the face of the coin, it will show you what a die looks like. Look at the opposite side of the foil, then you will see a copy of the face of a coin. Dies are negatives, coins are positives. That is how they are setup to create coins.
Note the devices are mirror looking on a die. The rim is formed on the gutter on the outside edge of the die. Note it is lower than the fields. That is how it forms the protective rim to make the coins last longer in circulation.

How are incuse devices created? Why does damage not affect them, unless the contact marks are real deep?
