So do I. It just makes sense.

I don't disagree at all. A coin that you or I might buy raw in theory has been handled recently (for photo's if no other reason) and easily could show handling marks later as a result. There's always the chance that a thumbed coin might clean up and look terrible after an acetone soak but it shouldn't show fingerprints as a result.
I do it too. Burned once
Always for me, pesky fingerprints show up years later if the problem wasn't taken care of before slabbing.

I am in the same crowd. Everything gets an acetone bath before submitting. it generally stops a problem before it shows up.
Doing an acetone soak/wash on coins is an excellent way to avoid possible future issues. We have no way of knowing what may have affected a coin prior to our acquisition... unless directly from the mint (and still, I have and would, wash ASE's immediately, since it 'may' prevent milk spots) or slabbed.

Absolutely no harm in doing unless there is a little wax or grease covering a minor issue. And I'm surprised that even as busy as the top grading services are, why they don't just go ahead and do it or have a box to check for the go-ahead. A month plus wait for economies, wasted money, increased frustration, more shipping another submission fee and paperwork not good for the hobby.
At what point is _not _acetoning a form of doctoring?
I famously (in my mind, at least) did nothing to this piece before sending it in. Could it have been helped? Could it have graded higher if I had? Or would some of the character or originality been lost if I had?

I typically do not use acetone. However, the only way to ensure a grade with a coin that saw long term storage in a soft flip , is to remove the PVC that bleeds onto the coin.
How long do you soak it? Then do you rinse it with distilled water ? I know this is dangerous and must be done in a well ventilated area.
Who asked you that
I just roll a Q-tip , with acetone, over the coin. Or, you can dab it with a cotton ball. Need I say don't rub it
The length of time in the acetone depends on each individual coin. If there is nothing obvious it may be for five minutes, however if there a contaminants on the coin it can be much longer. If there were contaminants on the coin, you can rise with distilled water, otherwise the acetone will evaporate off of the coin on its' own.
Thank you !
This one earned the cac sticker but downgraded a point after the dip: http://i.imgur.com/ranKGuj.jpg http://i.imgur.com/gS9KqlM.jpg After: http://i.ebayimg.com/images/g/PH8AAOSwvqlZehEH/s-l1600.jpg http://i.ebayimg.com/images/g/8CAAAOSwAANY7TJe/s-l1600.jpg
There was something on the surface that came off and downgraded it. It kept grading 62 at both NGC and PCGS, though ICG called it 64 the first time and 63 the second. What a loser for me.
And California does not allow acetone to be sold.
Perfect reason not to put coins in acetone if you are not a skilled grader. The "something" is called "skin." The beautiful, often semi-iridescent haze that seems to float on the surface spreading a "frost-like" reflection and hiding rub, hairlines, and marks. There ain't no way an MS-64 at one major service goes to an MS-62 at two others w/o someone messing with it.
If you know the "coin dipper" who ruined the eye-appeal of your coin, you might suggest they practice on "junk silver" for a few years.
I use a small glass dish and fill with enough acetone to cover the coin....cover with my red book for a few minutes and then remove and drip a bit more acetone with coin held at an angle...get's the dirty acetone off.
Set on edge and let dry.

Simply par for the course.
It is a wise practice to do an acetone rinse on coins before there slabbed. The Flying eagle below was submitted by me with a lot of coins around 15 years ago. Over time the PVC has became more obvious.
There's a doctoring trick to be inferred from the above information.
Proprietary, but a 5th-grader is likely to figure it out.
Clue: meniscus
Colonel your epidermis is showing...
Squalene
I believe we say God Bless You after you sneeze
Squalene, shark oil. Special properties, but is it better than whale or other exotic oils like krill?
Never checked on their emulsification by various solvents.
Well, sounds like it is working well for you. On another forum there was a "collector" who claimed he zapped his coins with "heavy duty oven cleaner" before sending them for authentication....Hmmmm?
