I basically have coin fever after getting a dud box todayoldest one is a 1963.I found the 2021 first thinking it was just a gash when I found an exact identical mark on the 2019.Im now questioning weather they are something more or just some heavy hits(damaged).First picture is the coin on the left the second is the coin on the right.My phone cam isn't working right but will try to get better pictures if needed.
Looks like Its raised on the lower side. Displaced metal = damage. You can confirm that by rotating it in a light source and looking at the shadows. Sometimes it's hard to tell from pics
