What's All Over My Jefferson Proof?!

Recently I got a 2017 S Jefferson single out of those enhanced sets that came out this year and it had brownish marks that look like what yours has.
I soaked it in acetone and it went away but not immediately.
I was thinking it was some kind of oil that they lube the presses with that got on the coin.
I also am liking using a can of electronic compressed at a distance to blow dust out of my capsules and off my coins.
Just keep a bit of distance with those cans of air and don't shake the can.
The can gets cold, give it a rest.
Cold equals condensation.

That's just one crappy looking proof all around - I'd return it if possible.

I bought it along with the Uncirculated Dollar and I'm happy with that one. I don't know how to approach returning half of the purchase or if it's even possible through ebay. They do offer returns, though.

Hmmmm...

I normally shy away from returns but, I'm not sure I'm comfortable trying acetone on a proof like this. In the end, it's not something I would proudly display so there needs to be some sort of action. I could resell it but, that creates the same potential problem with a new buyer.

Maybe I should just return the whole shebang and forget the deal I thought I got for buying both together.

Edit:




Unfortunately, I agree. It's horrible for a modern proof. I didn't buy it with the expectation of trying to rehab it. I think it's settled. A full return is in order and I can use this to select a better example individually. To be honest, I think I like the looks of the UNC dollar over the proof for some reason.

Post-edit: I messaged the seller about the situation before opening a return request. I know as an ebay seller, sometimes a partial refund is way easier than going through the whole ordeal over again to sell it. They have 30-day returns so, it will be resolved one way or another. Thanks for the input guys!

I messaged the seller and they offered no recourse other than returning both. I started thinking (rabbit hole) and had a change of heart. Their pics were clear enough that it was my mistake for not asking about the marks before I purchased. I also hate returning things and would much rather resell something I don't like.

So.............. I told the seller I'd keep both. It's like a purposefully self-imposed learning experience. I decided that trying to rehab it in the safest ways I know would be better for my curiosity/knowledge than sending it back. Now it is in an acetone bath and will remain there for a good time.

After all, it's still silver so I won't destroy all value and I got it for a good price compared to current individual listings. I will, of course, share my results so it may be useful to others in the same predicament.
