I really don't understand what NGC took offense to here on this coin. It just looks like an often encountered "paint splatter" type of toning. Any insights appreciated as I'd like to understand how to spot this and to avoid it. But I really don't see anything all that odd...is this "damage" just hard to see in photos, whereas one might need a loupe to detect it? https://www.ebay.com/itm/1937-D-Mer...254825910289By the same criteria (and I don't know what criteria that is, only the look of the coin), would this coin also be considered to have "environmental damage"? https://www.ebay.com/itm/U-S-1916-S...047675.l2557 |

Hard to say how "built up" some of this spotting might be, as opposed to toning splashed.

with the 37-D I really wouldn't call environmental damage but the eye appeal is really low . The 16-S I just don't like at all no matter what you call it .  |

It must be remembered that toning, in this case not so attractive, is really just a mild form of corrosion, and if bad enough, will affect the surface to cause localized damage. Same with verdigris pitting on bronze coins. My guess is that NGC may have considered that localized toning was borderline bad enough on both coins to raise a 'details' designation, one lucky enough to escape that designation, one not so lucky. I have an otherwise MS-62 (Indian .925 silver rupee) in my collection with obvious corrosion pitting bad enough for it not to be graded at all. Very little premium above silver value only. Essentially, a form of PMD. |

I had forgotten that I did notice the second coin (1916-S) had been listed by another seller back in October, and this current seller had re-photographed it. The pics look a little different (there's a slim chance you might like these pics a tad better T-BOP): https://www.ebay.com/itm/1916-S-Mer...047675.l2557So yeah, I'm curious if NGC or PCGS would likely consider the toning on the 1916-S to be "environmental damage". If we could see the 1937-D a little better, perhaps we could see any pitting. Just to clarify sel_69l, the 1916-S is a raw coin. |

Simply, the "splatter" toning has entered the field; removing it will pit the surface. For the '16-S: that's dippable-it's all surface junk

Without the pieces in hand to see them, its not likely we can know for sure. We cannot see the coins in 3D to know if the first one's spots are just on the surface or not. Do those spots, when the coin is in hand, hide small pock marks on the surface? We do not know.
Zooming on on the first one's OBV, the pic is not totally in focus, but it looks like there are some small pock marks at least on the rim with some of the black.
Its easy to guess and say its not real damage, but comparing pics instead of coins makes it difficult.

Yeah, but NGC did have the coin "in hand". I'll take their word for it for ED. The '16-S: I've seen many original-skin coins such as this one, so I'm comfortable that it will "all come off".

Also consider the original intention of third party grading, is to only certify coins that would be market acceptable for the grade. Even if the surfaces here are intact and just afflicted by ugly toning patterns, someone buying a NGC Mercury dime at the grade sight unseen would surely be disappointed, so this is likely why they gave it details |

For the '16-S: that's dippable-it's all surface junk How/why is the 1916-S "splatter" toning evidently not the same as on the 1937-D? By the way, dipping will also destroy originality. Doesn't the 1916-S toning speak to this coin having gone through "something" during its existence, not simply plucked from changed and placed in a completely sealed environment for the last 100 years, or worse dipped at some point. Why do you suggest that removing toning on one coin will pit the surface, but on the other coin it will be fine? How can one tell this just from looking at the surface? I asked the seller of the 1937-D if he could tell any reason why they detailed it: "It looks to have some sort of raised substance on the right half of the coin" Edited by one_fine_dime

In either one if mine I'd simply dip to get rid of toning. If my coin, I do with what I want.

I would never dip a circulated coin unless it was junk silver . |

ONE FINE DIME - before I conserve a coin I look at the toning or corrosion areas to see using profesional judgment to remove these areas or leave alone using a stereo microscope with mag power up to 40X based on its depth of penetration into the surface of the coin, token or medal.
