I'm too chicken to try it out with any of my proofs, but does anybody know? Dipping a regular coin is supposed to strip the luster and do all sorts of horrible things, but will dipping a proof coin cloud the reflection? Put spots on it? Simply remove unwanted toning?

I am sure it has the ability to remove the mirrored fields and dull the frosted devices, but I am not going to try it just to find out.

The same statement about dipping applies to Proofs as it does Business Strikes: the coin will tolerate a certain number of seconds in dip over its' lifetime. No two coins will tolerate dip similarly. Until that cumulative limit is reached, you probably won't know it's been dipped at all. When that limit is reached, an additional tenth of a second destroys the coin forever. The only difference with Proofs is that limit is reached sooner, maybe only two or three seconds, and the damage is all the more obvious. Feeling lucky?

What type of coins are you thinking of dipping.
I might be getting ready to dump some coins at the bank. I could maybe do a test and see what it takes off and how long ... depends on what series coins you are thinking about.

Yea, you ought to be able to find a cheap proof and experiment

Quote: What type of coins are you thinking of dipping Proof coins. Doesn't matter the series. I have plenty of them and some have spotting and/or toning that I don't like. If somebody told be that dipping wouldn't have any adverse affect on proof coins, I'd be willing to test it out. Based on what SsuperDdave said, however, I'm not feeling particularly lucky. Do you typically dump proof coins at your bank?

Quote: Do you typically dump proof coins at your bank Yes. Couple times a year I am in a LCS, and get offered a deal on proof/mint sets. Quite often I break them up. I might be working on extra Dansco albums or just putting rolls of proof coins away. One idea came into my head lately. Put rolls of silver proof State Quarters away. For example 8 sets of 2004 proof silver quarters will make a complete roll. Not sure why I want to do it .. just something different.

You do have me curious about dipping proof coins.
I will have to see if I have any that have spots and give it a try.
In the past, I know I have dipped some proof Ike's. I remember not liking how they came out.
As SuperDave posted .. about dipping them to long. I must have went to many seconds ..

This.......  When I first started collecting I dipped this proof because of light spotting. Better left alone.

ODD that so far no one has mentioned dipping in WHAT? Exactly what are you saying for a solution to have a coin dipped in. IF dipping in distilled water, acid, Vodka, Acetone, Tomato Juice, etc. all could have different results. And the duration of that dip also could well make a difference. I've dipped Proof coins in Acetone in the past with no problems. I've dipped Copper coins in Sulfuric Acid and, guess what? So much depends on what your talking about.

Talking about Dip. Surely you've seen Who Framed Roger Rabbit?

Quote: Data from the work of others is dangerous, not useful. I do not totally agree. In the little problem solving training I have had, is the data to use from others work .. is what did not work ....so you don't repeat it. But of course your right .. in this case each coin would have different results. What might be nice to know .. is that max you might dip a coin. From coins I have dipped, I seem to get different results with copper, nickel and silver coins. (have never tried dipping a gold coin) After bad results with copper and nickel coins, I pretty have given up on dipping those. But would be willing to try again. My thoughts are, for a coin like a proof Ike, with milky toning. The amount of time it might take to dissolve the toning, would make the mirror surfaces dull and not very attractive. Again ...just my opinion ...

Just carl has a point. It should be stipulated that the term "dipping" has a precise numismatic definition involving the use of a thiourea solution to acid-strip the surfaces of a coin. The fact that the term can be used with other connotations doesn't change what most experienced numismatists hear when the word "dip" is used. The "standard" dilution considered "full strength" is what you get straight from a container of E-Zest. This stuff works well on silver and nickel, but in my experience (  ) turns copper an ugly unmistakable orange. One may assume (although I've heard stories of outliers) that a maximum of ten total seconds in dip will kill a coin. It may be diluted in water, and the speed of the effect is diluted in nice linear fashion. It's a subject which should never be discussed casually, as dangerous in its' way as acetone is in another.
