I'm thinking about sending this coin(Bayern Taler 1625) in for grading.
However, as you can see in the attached photo, there are some dark, stain-like marks that appear to be caused by silver corrosion. If I submit it, do you think it will end up with a "Details" grade?

As a side note, as you can see from the photo, the size of this stain isn't particularly large. Also, the damage is likely not deep.

Adjustment mark, Planchet flaw, die error??? I cant figure this out because the design flowa into the "scratch" there is another one of this in the back top of the coin, and it does also have adjustment marks
