Dipping is doctoring in my opinion
<< <i>They are generally referring to E-Zest, correct? >>
Correct for me.
I consider Acetone just a rinse. Or Wrinch as the say in west Texas!
<< <i>Dipping is doctoring in my opinion >>
Could make me a pre-med student but then I don't consider E-Z-Est doctoring as much as I consider it conserving.

<< <i>Dipping changes the appearance of a coin, it is typically done to enhance the coin's eye appeal by changing it. I don't condone dipping. If there is active pvc that is currently ruining the coin then by all means perserve or conserve it but that is as far as i go. >>
Dipping does NOT remove PVC.
<< <i>many different kinds of dip - there almost all acid based .
Dipping is doctoring in my opinion >>
ALL dips are acid based, and PCGS does not share your doctoring opinion.
<< <i>Is acetone considered dipping? >>
No.

<< <i>I've heard people talk about MS70, what is that? >>
"MS-70 is a blend of industrial detergents and surfactants designed to remove surface contamination from metal without disturbing the metal surface itself.
Surface contamination can be seen as PVC, tarnish, fog, oil, dirt, etc. "
Everyone is entitled to an opinion, just do not confuse it with facts. DIPPING IS NOT DOCTORING. I would agree, however, that the dipping process can be taken beyond the intent (to remove contaminants) and (if an aggressive dip is used), certainly cross over into the area of doctoring. Again, there are always purists, and each is entitled to believe what suits their personal agenda. Cheers, RickO

I like the way ricko put it. If you don't believe in dipping, call yourself a purist. But don't call everyone who dips a coin a doctor. --Jerry
dip UNC coins... again I think there are many different opinions on this subject... I don't dip coins
but if I find a coin that has alot of dirt or other stuff on the coin that makes it unappealing to the eye...
then I will try soapy water first, then & only then will try acetone...
I also know many many people who use MS-70 on coins... mostly to get off the film that mainly comes
from the plastic the mint puts the coins in... (as for me, I seldom ever sell coins... as I am a collector)...
Again there are many people who have their own opinion regarding dipping or using either acetone or
MS-70 or other methods. I know many an oldtimer used alot of different things to take off dirt or other
foreign material... such as coffee grounds for copper coins...

I would never do it but not because I am a purist but because
I am cluess when it comes to the process and basically I am afraid
of doing more harm than good. I have tried acetone a couple of
times and was not happy with the results.
Its probably ok to use a neutral solvents but in my case I will leave
it to the experts to do.
I share Paul's view; dipping most often removes the "original skin" of a coin. Ask some of the renowned collectors, like Stewart Blay, their opinion.
It’s like you can't be just a "little bit" pregnant. I think the entire issue of dipping and coin doctoring will come out as PCGS pursues legal action against the copper coin doctors.

This statement is entirely unsupported by fact, and merely a supposition. I have many GSA dollars in the original holders that are blast white. And there are many more that have been stored properly and not acquired surface decomposition. Such a statement may sound profound, but cannot be proved or even remotely supported. Cheers, RickO

Original skin is a combination of old rinse residue from planchet preparation processes and machining grease. Sometimes it's good and sometimes it's bad.
Horribly toned coins that are splotchy and appear damaged deserve to have those residues removed.
Silver Eagle's, due to their inherent tendency to milk spot, require a dip. Most modern Silver coins require it because once it's entombed, it's impossible to correct.
Crusty classics don't deserve any type of dip other than perhaps an acetone rinse to remove unwanted oils.
It's all relative folks and solely based upon preference first and know what to do second.
If you're a purist, fine but please try NOT to condemn those that don't entertain such lofty opinions.

"Original" with regards to skin is a fuzzy area. I've often wondered how a rainbow toned coin could be considered "mint state" if you take the literal definition of "mint state" as being in the original condition that the coin left the mint. Toning is a reaction product of the surface metals of a coin with moisture and gases in ambient air. As a result the "Original surface" of the toned coined has chemically changed into something different from when it left the mint!
I agree that dipping is a good way to conserve a coin, especially with those ugly haze-covered proof Ikes. A dip on those does wonders! But, overdipping coins will ultimately strip the original mint lustre, leaving a dull finish without eye-appeal or value.
I wonder if the automible purist would appreciate a rusted, corroded, pitted old antique auto over one restored to original specs with original parts.

To dip a coin, hold it by the edges between thumb and forefinger (or middle finger if you’re in New Jersey), then bend backwards from the waist, bending your knees slightly to maintain balance.
You have now “dipped” a coin.
In the late 60's and into the 70'S. When I was in college and visiting alot of dealers. I saw BM dealers dipping coins like crazy. One dealer had a small back room closet space were he had a mini facotory so to speak set up to run alot of coins through the "Jeweluster" dip, rinse and pat dry with a towl. Everyone with silver coins was doing it. He was unabashed at doing it , it did not have a stigma. Imagine this being done all over the country when there were alot more BM shops than now. Yes alot of coins have been dipped, probably more than once.

People forget that 99% of the collectors back then demanded bright, white silver coins. Dealers were just meeting demand. If they didn't dip the tarnish off their coins, they couldn't sell them and they would soon be out of business. So blame the collectors. If they demanded original coins, the dealers wouldn't have ever dipped them.

I would try acetone first. Soap can strip a coin of original patina and make it less desirable, and lower its grade. Acetone will not strip the coin -- it will remove PVC and other contaminants.
