Pictures really are to blurry to tell but by the looks of it to me just a large scratch.Yes they are very common and most don't add any value.
Gregg, you need to post photos FULL IMAGE (after uploading a photo, two buttons appear; Thumbnail and Full Image. Click Full Image.) so we can easily enlarge and examine them.
Yeah, that just looks like a scratch on the coin, not a die crack. Try feeling with your fingernail to tell if there is a raised area.
