I see a line in the scalp of the King (obv.), and an irregular curved line above the tree. (rev.)
From these pictures, I cannot tell if partial flan failure or scratch on the coin.
Would need closer up micrographs for that.
However, if you knew what to look for, a hand held visual inspection, with the assistance of a 10x loupe, may be sufficient to determine if scratch or flan failure. You would need to form your own opinion, because you would be doing the hand held inspection.
