I understand no one wants to risk an opinion?

I wanted to ask about this one because I found it very attractive. But also because of those tiny scratches in the FR spare.
It is not the first time I have seen a coin with otherwise perfect surfaces and bearing that kind of disturbance in some small area.
I have been wondering how these happen.
If they may happen in the planchet and not be erased by the strike?
If they may be a product of the minting itself, some garbage in the die?
If they are later damage due to some dirt or grain scratching the surface.
And if they condemn a coin for most collectors, or are seen as a minor distraction.
This was an especially good coin to ask about it because the oxidation there makes it more visible. I have seen several other mint state coins with similar small surface marks, and over time even added some to my collection. Always assumed mint damage. Here it is a "superb" coin and there is no more to tell.
Only recently I became more aware of the grading practices in North America, the Sheldon scale and also those classifications of 'details'. I have wondered how this was looked at there.
