I am under the impression that dipping a coin will eliminate the original surfaces, and therefore the original mint luster. Am I correct in that understanding? I'm not talking about acetone or xylene or water, but coin dip stuff.

That's what I've always understood.
If it doesn't completely remove the luster, it would certainly reduce it.
It would have to, since a dip in E-Z-est or similar jar actually removes minute amounts of the metal.

I wouldn't experiment with a valuable silver coin right off the bat. Maybe you have a common BU silver coin, like a Roosevelt dime to try it on first. I have thought about using it diluted on occasion. I don't know what I would dilute it with. The longer a coin is in the stuff the more gets taken off the coin I would bet. I have a jar in the basement, I think I used it on some artificial toned Silver American Eagles I had at one time. I don't know where it is now. In a box someplace? But all coins are individuals. One may react completely different than the next. |

One dip does not affect the luster to a noticeable degree. But then coins tone again and they get dipped again. Eventually they get dull. If the mint luster is great looking, deep and vibrant, a dip will remove the toning and not hurt the luster. The dip should be for about 1 second and quickly followed by a rinse in tap water followed by a rinse in distilled water. Dry with some compressed air and leave on a towel for at least a few minutes.

I have no plans on dipping anything. I have a coin that still has luster along the rim and against the devices, but everyone says it was dipped. So I'm trying to figure out if it was indeed dipped.

It will, eventually, but careful - and lucky! - usage will not effect luster. The "lucky" part is, cumulative time in dip adds up, and you won't know if it's been dipped before or not. You may have a coin which has never been treated, or you may have a coin that's already two seconds short of losing the luster forever.
And that cumulative time total is not the same for all coins, even coins of a given mintage, and you won't know one to another what that particular coin's tolerance is.

That's a good question. I have never "dipped" a coin but am having mischievous thoughts of treating a modern commemorative silver proof with a thiourea-based dip I have. Hmmm...

Dilute with distilled water. One quick dip on a BU coin will not show a lack of luster, but it does remove a minuscule amount of metal. John1  |

 show us the coin you are concerned about. There are plenty of knowledgeable folks that could give you a good opinion. |

This is the coin. When I put it up for grading here, everyone jumped on the dipped bandwagon. I've been looking (staring) at this coin, and there is original luster all around the rim on the obverse and reverse, around many devices (stars, between many letters, etc.), as well as other smaller areas. And the reflections are cartwheeling in those areas. Moxking, you even said Quote:
Extra Fine, details, cleaned. A very long dip. I just honestly have my doubts about it having been heavily dipped.   |

I'd call that a certain victim of overdipping. When was the last time you saw a circulated Bustie with that kind of surface finish? The reason luster still clings around the stars is because that was the only place it still existed before the dip. The color is totally unnatural, and the remaining dark areas hint that the coin was pretty black - as Busties get - before the dip.
Not a chance that coin survived 195 years - after circulating - with that surface finish. Not. A. Chance.
