The 1910-S Shows a finger print.
They may have been dipped. The wear and the color don't seem to match. The 1919 looks like a pretty good one. Maybe a bit better grade for this one. The 'S' mints a bit lower. VG because of the rub on the busts. The Philly ones are more desirable. F+ on some of them.

They may have been dipped if the color is off, but it wasn't Acetone that did it. Acetone won't harm them. It might help the 18-S Woody, if that's something on it instead of abrasion. Here, try some of this...  |

CoinMaster! Are a major user of acetone? Looks like the super-economy size... Several of the coins seem to have been cooked or microwaved..they have a curious tiger_stripe appearance on teh reverse, like they were place on some for of grill or mesh and then heated.    to me this is off-putting and doesn't enhance the coin's value. What is the process anyway? David |

The last pics you're showing look like unknown source environmental damage to me. The 1918 in your first pics looks like a Woody planchet error, thought to be caused by an Improper Alloy Mix.  |

I don't use any. Who knows what will happen in time with this? Down the road, it might be determined to have been a mistake? I stick with the basics. Mineral oil to remove gunk around the devices only as needed. Otherwise I leave them alone. If a coin looks so bad I would not buy it, I return back to circulation. To altered a coin that you are tying to improve the look of, usually back fires in the end.

I listed the 1910S with the fingerprint at ebay, and not surprisingly, the interest (reflected in the current auction price) is underwhelming! David |

I know that some people have substituted Methyl Ethyl Ketone (MEK) for Acetone because a subsequent rinse in distilled water dissolves the MEK. Trace impurities in any solvent could cause significant damage to coin surfaces.
That said, I limit any surface cleaning to distilled water, and that only for run of the mill circulated coins. Valuable coins need proper conservation, and the risk of home remedies exceeds the reward. JMHO.
