Note a die scratch, but a coin scratch. It looks like it flows behind the dvices, but the devices are incuse and deeper than the coin scratch. (The devices that are on the outside of the
ATB are raised on the die, incuse on the coins. So scratches and damage affects the field, but has to be real deep to affect the incuse devices)
ID: EPU on Shield cents are also incuse:


The damage has to be this strong to show on the devices of these incuse ones.
