Have you dipped clad coins in E-Z-est or is this something you just heard or read?
Because I have dipped clad coins in E-Z-est and it didn't damage the finish.

This is something I would never want to do without some practice and accepting the possibility a coin will be forever ruined. That being said, I believe the solution needs to be diluted, the dipping needs to be done quickly, and the coin needs to be thoroughly rinsed to remove all traces of the acid. Your experience (past or future) may vary.  |

I am far from an expert in dipping, as I have never done it myself with an acid or base. But just from a mechanical perspective, I have to imagine this attempt would to end in disappointment. The mirror finish of a proof is from planchet polishing and work hardening. It is probably very shallow. That thick toning is a chemical interaction with the coin's mirror finish. If you chemically strip that away, I think you will end up with a visibly matte surface. Dipping probably works on business strike coins because removing a layer of metal results in something that closely resembles the business strike finish. This seems like a thread where BadThad or Sap will have some insights. You can buy proof Kennedy halves in that era from sellers like Sclora on ebay for about $4. If you really hate the way these look, I suggest selling them or giving them away and just buying replacements. Some folks might be really keen to own heavily toned proofs (not me, I'm a blast white kinda guy). They seem like a good contest giveaway. |

Since they are probably hooped due to enviro
damage , you have little to lose.
Probably storednear a source of sulphur, ie
furnace .
Try this , quick 10 second rinse in Sudsy Ammonia,
then , wash with warm water.
Or MS70 will do the trick .

Before and After of a dipped dollar  I use wood tongs to submerge it 2-3 times quickly in E-Z-est Then I dip it in distilled water Followed by multiple dips in 90% alcohol with a reposition of the coin in the tongs The final step is to dry the alcohol with canned compressed air with a reposition of the coin in the tongs so there aren't any trapped chemicals between the tongs and the coins edge Here is a pic I just took of the coin I dipped a couple years ago The spots on the right are camera reflection and it's a bit grainy because to not get a lot of reflection on the coin I have to take the picture from about 36" and use the 3x focus setting  Edited by Boba Debt

well of course the 2 coins would display different, as one image in viewed from the top down and the other on an oblique angle.
A more accurate comparison that the 'after' image would also be flat and viewed from the same angle as the 'before' image.

I wouldn't fiddle with these, the probably of ruining them permanently is too high. If you don't like the toning, sell them and buy new, untoned examples. I believe these are relatively inexpensive. Spare yourself the money, time and frustration.

It tried to photograph it straight on but you could see everything, the phone,me the ceiling fan, in the reflection of the field. I wish I had taken the before pic at an angle because you could see the haze from any angle. Edited by Boba Debt

One thing to consider is the cost of the product that will exceed the premium on both coins pictured, these coins are impaired beyond revival and even if they were in a better condition no matter what product you use on PROOF coins 99% of times it will not produce any result.

@Boba Debt please start your own topic for a better attention.
The OP's coins are completely defferent showing heavy hazing /toning. We are discussing the nominal affect of the cleaner on proof coins. Once a proof coin is impaired there will be no turn around.

@Boba Debt please start your own topic for a better attention. First of all, YOU are not a moderator so stay in your lane. Secondly, the OP was asking about Acetone to clean a coin. I clean a lot of my coins because I don't care about resale value. I have used just about every chemical available from acetone to silver polish and I have real world experience with each of them. I also have cleaned old circulated coins in far worse shape than the one posted so I was offering him a solution based on my real experience, not what I have read about the different processes available. Thirdly, Dearborn, who is a moderator, posted a reply stating that the angle of my after image should have been the same for my sample coin to get a better comparison, so I obliged him |

It was a friendly suggestion since we had already seen the examples of your cleaning and remember this is an open dialog Forum so it is important we treat one another with respect regardless of our personal egos.

Thank you Boba Debt for the additional image. I'll relocate it to your other post up above for a better comparison for the OP.
