I know nothing about silver  But knowing chemistry and grading and after looking for 30 seconds I decided if one is MS it is the ugly blue with white spot and if one is toned after 3 months in the open it is the second one Since I know nothing of silver I am not afraid to be totally wrong  |

I honestly do not know why 1921's don't tone the same as the previous years - I would imagine it has to do with changed washing processes pre- and post-minting. However, although I've seen a few classic bullseye-toned 1921's, most of them follow this pattern. This was the top coin, when I bought it in May (note the mark on the cheek for confirmation):  Since, it has sat, reverse-up, on my computer desk. I have done absolutely nothing to it. If I'd doctored it, the result would have been much better. It's not like I don't know how.  The desk is a standard Staples pressboard cheapie, and it's 5 years old. The bottom coin is an NGC MS64 1921-D VAM-1I (look at the N in UNITED). It was purchased for healthy MS64 money from a prominent and widely-respected dealer. My coin was an experiment to see where the toning on this coin might have originated, because I feel like you guys do about the toning. I only bought it because it was near-Condition Census for the VAM. |

For the record, I did not allow my coin to continue looking like that. Here it is, ten minutes ago:   |

Wow that's a big change. What did you think when you first turned it over and saw it. Would have freaked me out. Not into heavy toners. I wonder if the glues or chemicals in the press board had something to do with it.

Dave, Just kind of curious,had the desk been polished or waxed near the time you laid the coin on it. Also what did you do to clean that coin? Much better. |

I already knew what was goin to happen - this isn't the first coin that my desk has toned. See this thread: https://goccf.com/t/6648I believe you're right about the desk. It's never been waxed, nor do I use cleaning chemicals to clean it, as I'm allergic to many. Given that sensitivity, I wonder why I've shown no ill effects (depending on your definition of "wierd" ). I used six seconds of E-Zest to remove the toning. As you can see from the full-sunlight pic, no luster was lost. |

I have always wondered about this ezest stuff, did you dilute it with water, did you put it on the coin with a q-tip or did you just submerge the coin

Although some use it diluted, I just hold the coin by the rim with rubber-coated tongs, and hold it in full-strength solution, swishing slightly. The point, in my experience, at which physical surface damage begins (surface differences visible at 200x with my QX5) is about ten seconds. Today's dip was the longest I've ever done with a coin I was not trying to destroy, and I don't believe I'll ever have to match this one, because I don't buy toners. When considering such a step, always make sure an acetone dip doesn't solve the problem, since you can pretty much leave silver in there and forget it for a few months. |

This is funnier than you might think stmpcol, as I was about to say that I had been into coin collecting so long that this kind of damage don't interest me in the least. sorry but that is how I feel about this topic. |

I have some 1878 VAM's that have horrible finger prints and acetone will not touch them (beleive me I have tried) and have a few that is just plain UGLY with the toning on them and always wondered how to do this jewel luster/e z est to get rid of those, I heard it will get rid of both rather quickly |

I've not had a lot of luck with fingerprints. Have you had a look into another product, MS-70, yet? If not, do - it's a surfactant rather than a acid, and as such a less, um, aggressive step than dipping. Dipping, even in my liberal opinion, is a very final option which should only be used rarely, and never more than once on a coin.

If a good solvent like acetone does not remove a fingerprint than a glorified soap like MS70 will not either MS70 leaves a layer of deposit that can be seen under sightlighting so you better rinse thouroughly with distillated water afterwards I am currently reading an old book about how they made the Hale telescoop in which they describe not even acetone got the fingerprints of the main pyrex glass They had to burn them off  |
