A few years ago I bought a complete set of Kennedy halves online. The ad had poor pictures but the price was right. In general the coins are really nice and choice BU plus. It was put together by someone who knew what they were doing but sold by his heirs. It is stored in a Whitman Classic album. Some of the coins (especially proofs) have an ugly brown toning on them. I've never had coins do this so I guess it's environmental from where they came from. Is there anything I can do to remove or arrest the toning and protect the ones that don't have it without damaging the coins? Acetone dip, etc.. *** Moved by Staff to a more appropriate forum. *** |

Photos would help. Acetone won't remove toning, but a quick dip in a silver dip like eZest might remove ugly toning on a mint state coin. But you need to be really careful not to overdip and destroy the underlying luster. As a general rule, if you're not sure how to do it, don't try.

@pmi, one thought I have is perhaps you can now greatly slow the toning process by properly storing these coins. Toning seems to be one of those "eye of the beholder" things and there might be someone who find this toning to be attractive. Just a thought anyway.

 E-Z-est (Jewel-Luster) or common silver tarnish dip would do the trick, but over dipping is a real issue, as is proper removal and rinsing. I wouldn't recommend anyone that does not have lots and lots of experience even attempt it. I've been around coins for almost 4 decades and I don't do it myself, I've tried and every time I've messed it up. So I leave it to others I know can do a decent job.

Anything more that just Acetone, I wouldn't bother with. Why take chances. Leave well enough alone.

I definitely would not use silver dip on your Proof coins . If you must , a short soak in pure acetone may help but it will not remove the ugly brown toning .  |

Additionally, if the toning is deep and dark, then eZest may not even remove it completely. I found eZest is good for very light toning and fingerprints.

Lets see some pics, I personally prefer toning.

Practicing with e-Z-est on normal coins can bring a feel for how to use it. Get some common coins with same luster and then experiment and learn.
A literal 1 second dip and immediate (did I say fast?) rinse, then pat dry.
Then take a 2 second dip with anther like coin, then 3 seconds etc. gives a feel for what it takes to overdip a coin and ruin it.
Practicing with common clad is a must for using on clad. Practicing on melt silver (common dates in good shape - find them at a local store) works to help you learn.
The main enemy is wanting instant results so badly that patience is lost. "Just one more second" in the dip mentality (instead of sticking to the plan) can easily mess things up.
Also, despite what is said, you CAN tell a dipped silver coin's luster from one that has not been dipped. When side by side with an undipped coin, the dipped, while still beautiful for since, loses a bit of its natural silver luster. The grading companies will still grade a properly dipped coin.
As to using it on proofs. When I bought my first silver 1974-S Ike from a coin shop, it was foggy in the holder it came in. The owner (very experienced and respected dealer) dipped it and rinsed it to remove the fogginess. I cannot tell the difference from my other never-dipped proof Ikes.
But since there has been a caution mentioned above, practice with impaired proofs. Maybe clad proof coins react differently?
Practice and patience make perfect in this case.

I will disagree with this statement every time. I have shown time and time again that a coin that has been dipped properly is NOT easily distinguished from one that hasnt, if it can be at all. If you over do it? Absolutely. I do agree with everything else folks have said. Practice on impaired coins first. |

Yep my thoughts too, look at some things doctors can do to a coin that is virtually undetectable now says, dipping a coin without being able to tell, is an art, I've seen a few guys that can pull it off, I'm not one of them, so that is why I don't do it. Not dipping but a quick go through on this coin will show what some are doing now that is scary to me.
