1882 Morgan Toned

ok same deal... about a 75 minute soak with some occasional swirling. I took a Qtip dipped in acetone and rolled it around the edge. A little bit of grime came off. I repeatedly rolled it over the fingerprint area and the green areas with no apparent residue coming off on the qtip. It was still perfectly white afterwards. Do I need a much longer soak? The green stuff doesn't want to come off..

I'm going to say this again.

Silver doesn't tone that color. Especially not as the standalone color on the coin. Anyone who can look at the area above LIBERTY and see "toning" needs to recalibrate their knowledgebase. That's_not_toning.

There exists a remote possibility that it's verdigris (or some other external substance) and not PVC byproduct contamination, in which case acetone won't help (but won't hurt). But you have to assume it's the worst case, especially when the treatment can do no harm. However, 75 minutes is in no way long enough to make a dent in something this bad, if it's PVC. The first soak should be an overnight, and you're going to need something a bit stiffer than a Q-tip to work it. Use a toothpick to start with, preferably while the coin is still immersed.

I'm betting in-hand that color is more emerald green. A green not dissimilar to the darker areas on this coin;



Remember, these are amateur photos of a mishandled coin we're seeing. We also see some borderline terminal toning on the coin, with that flat black toning in some areas.

OP, does it look fuzzy on the surfaces, or does light reflect cleaning underneath them? I'm not sure, honestly, but my inclination is still to think toning, and while that color is rare and more indicative of Env Damage than natural, market-acceptable toning, it just doesn't look like PVC to me. Especially after some exposure to acetone, PVC lightens even more. I disagree regarding the effects of a 75 minute soak, I think that should have been sufficient to at least partially (Maybe only like, 2%, but still) neutralize some of the PVC, if that is what it was... whereas toning wouldn't be affected at all.

Look at the pictures in post 14... the reverse, that is toning around the eagles tail, not PVC. I'm betting the obverse has the same thing going on. OP, can you get a closer shot of the top of Liberty's head, where that green is most prevalent? Try to get it in the light and in focus much like the Eagles tail area in this image;

The further images - combined with thinking not affected by a total of 7 hours' sleep between Thursday morning and Sunday morning - leave me tending to agree with you. It's very_rare for a single color of toning to appear on a silver coin, save the original yellowish or the end-stage black, but not completely unheard-of. The last image posted has a tremendously different appearance than the OP, which scared me to death.

Low AU, big fingerprint, unflattering color, and common year...not seeing much of a premium for condition
On the other hand finding any Morgan with decent details for around $30 can sometimes be pretty hard to accomplish, if you like the coin 32 isn't terrible
