I agree, but the markings are still curious, and a little distracting. I don't think so, because of the way they start and stop at design elements.
While it is possible the coin has been cleaned I think it unlikely. For one thing the coin is slabbed by PCGS. And even though they make more than their share of bonehead mistakes when grading coins missing harsh cleaning is not usually one of them. I think this is another case of Proof like surfaces showing rough handling. If I had to guess - I would say this coin was at one point stored in a coin album with a plastic slide. And that the plastic slide was the source for the heavier scratches. The more minor scratches likely came from the coin sliding around on the felt of a coin cabinet in years past. Just my opinion.
Those are some nasty looking hairlines on that coin. I'm surprised it made it into a 64 holder!! Perhaps is was one of Dave Hall's coins!
With the date, those marks are easily attributable to adjustment marks, draw bar marks, etc. I think the cold rolling presses came into common Mint use in 1904. Before that, these marks are very common. Look at the direction on the observe and the reverse. They are almost identical in their direction, depth and they never cross a device but rather travel underneath. My $0.02.
Good observation, cris. It wouldn't surprise me at all if those were indeed adjustment marks. In that case, they would not be considered "post mint damadge". They would, however, affect the coin's "eye appeal".
Oh, goodness sakes YES. Whacked a few times with the ugly stick a coin that could easily have been queen of the prom. She now is still beautiful, but with really bad teeth!
Another possibility that was raised on a different forum is die polishing. It's nearly impossible to tell in a two-dimensional picture whether those lines are incuse or raised, but if they are raised, die polishing would explain everything, including the absence of marks on the design element. Everything raised on the coin is incuse on the die, so aggresive die polishing does not normally affect design elements.
