If it's carbon, it is not going to come off. If it is gunk, try verdi-care or Acetone. If you use acetone to try and get the gunk off, do not use fingernail polish remover type acetone. It has extra stuff in it like perfumes that might damage coins. Only the pure acetone should be used.
Where's the pics?
I deleted some pics and must have got these also.
Looks like a carbon-based organic residue. It also looks like a valuable coin in a PCGS slab....I'd leave it alone.
I could not resist the temptation! :nerd:
That coin has already been worked on- check out the necklace and headdress, you'll see the high points have less carbon where the lower points have more- that's not how it forms. I'd definitely take Thad's advice here. Not that you can turn a buck by conserving coins already in holders, but this probably isn't one of them.
I broke it out, cleaned a lot of it off, and had it reslabbed. The date pics are before and after. The coin looked like the "crud" was growing and I had to do something. I think more would have come off, but I did not want to risk getting a details grade coin back when I had it reslabbed.
The coin was my first major key date buy. I have learned a lot since then. I will not buy anything like it again. A dealer I know well told me it was my "tuition" coin. I paid for the learning experience. I bought the slab and not the coin. It is headed to the TSNS show to find a new owner before CDN bid goes down any more.
I'd never try to do anything to a key date, I don't care how much I think I can improve it. All it takes is one wrong move and you go from a number grade to details, or worse.
