The patination is what makes this coin, and I don't know if there is PVC contamination or verdigris. I'd like to send it to NCS but I'm afraid of the coin being ruined. Any thoughts?

the white 'stuff' is just scuffing on the holder.

 

this is the patination, unaffected by the above and pretty evenly distributed over the surface of the coin.

That coin has been fire gilt (i.e. gold plated) at the time of manufacture. These are worth a premium to some collectors.

 

 

Be careful how you conserve the coin. You can make it better, or you can make it worse.

I would recommend you try "Blue Ribbon" and follow the directions. If the green material doesn't come off with that, then it likely will not come off at all. In that case, I would leave it alone.
