Toning On Gilded Expo?

Anyone familiar with this?
In the OMP it was hard to see as it was on the seam where the 2 edges of the capsule overlap.
Is it fixable by NCS?

 

got a picture?? Normally toning is no problem at all for NCS

 

Yes ncs should be able to remove the tarnish, they always have on mine , but none of mine have been this dark. Good Luck!

 

You can't see the one in the OP?

To be clear, you have had toning on gilded gold Expos fixed by NCS?

 

No not on the gilded ones but on quite a few others , I dont know if it would be any different on the gilded or not , please let us know how it turns out if you do send them to ncs.

 

If is green residue. I ncs/ngc one 1/20 gold and return ms68. Withouth the residue.

 

I seen a lot of 2001-D silver 1oz NCS conserved but still with toning in the edge. I used to own one but I can't stand the toning.

If NCS can fix the toning, then they did a very poor job on a lot of 2001-D silver 1oz.
