I don't know. I've yet to send anything to NCS. I'd like to hear opinions from those who have. It would be really nice without the two larger dark spots on the reverse. No idea if they can remove those without affecting the toning.
Hi Wayne I have a book around here somewhere but I don't see it. I remember reading that carbon spots (copper carbanate) usually form on top of existing toning. So it may be possible to remove if the pitting isn't too deep or obvious. I've also have read that these spots occur like microscopic volcanos because the copper in the coin wants to return to it's natural state; copper ore. So the results could go either way.

You may want to do a search for threads on NCS - so far from what I've seen people have been pretty complimentary of the service.

What grade do you give it?
How do those two carbon spots affect the grade?
