Thank you for the opinions! I think that the copper spots will not annoy any serious collector of german kaiserreich coins. I would have graded the coin for a xf+ at the obverse side as well, because of it looks quiet fresh. On top of that the stucture of the neck is always ''uneven'' = It looks hacked up, but not all of the porosity is made by little scratches.
Are there furter opinions about the grading?
Greetings
Alex
