more inclined to say PMD because if you look at the reverse and observe it looks like damage on both sides in the same general area
It's a scratch/gouge. Notice that the metal around the scratch has been "Pushed Up". This is most noticeable above the T and in the fold just above the headband. That will not happen on a strike through
I agree that it’s probably a scratch/damage. As for grade, I think it would grade VF details, scratched. The TPGs give more leniency for this series than other series, but I think this one is a bit too far over that line to receive a straight grade. The variety appears to be B-4, R.3.
That would be a die clashing of both dies. A strikethough is when a foreign object comes between the die and the planchet when the strike is occurring, leaving an impression of the foreign object on the coin.
It's a scratch. I would think F15 but the grading services are less picky that I am it might go VF details, cleaned and damaged.
