Removing Toning From Proof Coins

I was thinking of buying a 1955 proof cent...the only thing is that is is heavily toned. Likely artificially. Is there any way to remove this toning and retire the original mirror fields?

Possibly. Cop out answer but true.

 

Try acetone. No rubbing.

 

I've never had toning removed with acetone. It will clean it but usually not remove toning. The only thing I've seen remove toning is a quick 3 second dip in e-zest.

 

I do proofs all the time with Kodak Stain Remover S-10. Full unmolested mirrors.

 

As a normal, it's best to just leave copper alone. Images would be great. With those maybe @Insider has some thoughts.

 

Copper cents?

 

Will it look ‘normal’ if I use acetone or e-zest?
Will be mirror fields be really foggy?

 

Here’s some photos.

 

Not one mottled like this one, but uniformly dark? Meh, mezzo mezzo. A little too much excess yellow, not enough magenta, when you look at the CMYK curves.

 

Copper is problematic to do ANYTHING with. Best to leave it alone.

 

Troo dat. Better to hold out hope it gets better. A lot of them do. Proof copper is a wonderful experiment of changes.

 

I really like this obverse. What has happened to the nickel?

 

Brasso......lol just kidding.

 

I would say to just buy one that doesn't require any conservation. May cost a few dollars more but well worth the guarantee you'll get what you want.

 

What nickel?

 

I would like to do some experiments dipping in sodium sulfite solution.

Acetone is probably the reason it is blue. Get some "Coin Care" and put it on the coin. Much of that color should come right off.

 

The chemist in me has to ask...Why would acetone turn a copper cent blue? Of course maybe if you put a flame to the liquid acetone, the heat would do it, but I assume you mean room temp. Jim

 

Acetone probably won't do anything to it, and after a dip in EZ est it will NOT look normal.
