That is known as conserving, not dipping. Best way don't use the stuff, forget you ever heard about it.

I don't see any problems with the Peace dollar you posted. The toning looks great but I guess I preferred toned coins over blast white ones. I guess it's while I prefer silver coins except for modern nclt ones that will never be exposed to air. |

It can't get much clearer than that. I agree, I have a friend that has dipped a lot of dollars in his time, he usually makes a big profit on the ones he does. I've dipped my share of coins, not with the success my friend has though. He was a past grader at PCGS and really knows what the TPGs are looking for, he is a wholesaler in the coin business and knows his stuff. I agree if the coin has any wear or rub on it it's not worth a dip.  If you do dip it, try a diluted solution with some distilled water rather than a full strength dip, do it fast, keeping the coin in the solution for no longer than needs to be, then follow it by a rinse in distilled water.

I actually have a bit of a conundrum related to this that has been ... well, I haven't had time to decide to commit.
I recently purchased an ex-Eliasberg 1883 No Cents Nickel. NOT a phenomenal coin. In the '96 or '97 sale, Bowers & Marena sold off 100 of them in one or two lots. Of course, since then they have been split apart. I have two, both graded PCGS 64. One of them has verdigris appearing. Were it any other coin or situation, I'd drop it in some acetone for a second and rinse it in distilled and call it a day. But the coin is encapsulated and as such, certified as ex-Eliasberg. This speaks to that "curators of history" idea... Not my coin, it was Big Lou's, it was part of a famous and historic collection, and that makes it something special, even though it would ordinarily not be something at all special otherwise.
I believe the answer is to send it to PCGS for conservation and have them re-encapsulate when done. Yes, it'll go from 64 to MS details, but it's the right thing to do. I've just been a little too busy to get off of top dead center to make it happen.
Don't mean to hi-jack the thread OP, just thought it was an interesting and uncommon occurrence that was worth relating.
As for my opinion, I didn't yet check the grading forum but I don't see anything worth risking a dip. I think the coin looks great the way it is. My humble opinion! Whatever you decide, do be careful (I'm sure you will be, but, just have to encourage it...)

Like most collectors, I hardly ever clean coins, apart from detector finds - and then I would only use abrasive cleaning on current coinage that needed cleaning before I could spend it. I have dipped a couple of silver coins in the past - one was a 1926 George V shilling and another an 1896 Morgan dollar. Neither are rare coins and they both cost me a little over silver melt. I dipped them because they had really horrible overall dark grey-black toning and it was almost impossible to see any details on them. Both coins were around AU, and I think they look much better for being dipped. I've been wondering about whether to dip this 1921-S Morgan dollar, which has sentimental value as it was given to my late Mother by an American friend many years ago. The blue/green colour is not a PVC deposit. Would you dip it?  |

Yes the removal of the copper oxide film or that 5% Cu. I perfected a cleaner that has no alloy effects to soft metals. I use it on coins of this nature like this 1921-S. They come out perfect. The technology behind my self made product is complex in terms of only changing the patina but not altering the copper or imparting hairlines. I never touch coins with full cartwheel effects. I rarely wind up with coins with problem surfaces and the CE's.

Numisrob, this all starting for me with detector finds, I still haven't dipped anything that I haven't found with a detector, but I'mconsidering. As far as your morgan goes, I bet it would look really nice dipped, but since it has sentimental value I certainly wouldn't want to change it at all!

No guarantees it becomes a Details coin. If they like the result, they'll put it in a "good" slab.

The blue/green colour is not a PVC deposit. Would you dip it? Yes it is, unless the color is wrong, and that coin is being eaten away. That's an unnatural shade for toning, and the color of an active PVC infestation strong enough to eat metal. If I'm wrong, acetone won't affect the toning in the slightest. If I'm right, that coin will be gone before you will. |

I agree that the Morgan dollar in question has a very bad PVC reaction. I've used acetone on PVC infested coins before with very good results. Edited by Celticsoul

Acetone is 100% effective on PVC. It always works.

Of course sometimes you don't know which way it will come back until after the dip, and if it comes back bad it's too late. Edited by Conder101
