Now your problem is that you removed the protective film that is on all proof coins - it's some sort of oily layer that prevents oxidation. I dipped an RCM proof coin in acetone once and then rubbed it gently with a tissue - boy, that made a mess.
But good luck with your auction.
Personally, I wouldn't buy a coin that has been taken out of its capsule. Since your first two pictures are of the coin sans capsule you're basically telling everyone that you handled it. Some buyers don't like that and regardless if you did anything to the coin or not.
Also, try to take a picture with less light reflection that one can actually see the coin surface.
