Grade in on Swiss Medal

I picked this one up a year or so ago and finally got around to sending it in, it had some verdigris along the edge so I sent it to NCS for conservation then on for grading.

Did you need NCS to remove it or could you have done it yourself with acetone and the likes?

I've been thinking about having NGC try to remove a finger print milky area on a proof coin.
Guess it can't hurt to try since it's not going anywhere grading wise unless I can get it off.
$20 sounds very reasonable to me considering the effect of the verdegris on the appearance and
and value of the medal...
It's just that I got my PCGS grades.
