Simple tarnish. However, in the coin hobby they have made tarnish marketable by calling it "toning."

Just to be clear, we're both talking about the black, smudges, along the rim in just a few spots on both?

The milky white marks? Those are called milk spots, they occur when the planchet wasn't properly dried after cleaning. There are other schools of thoughts like grease on the die. I honestly don't know but it's an issue with silver coins. Your coins are all bullion so in reality it shouldn't affect the price, but people collect ASE, so they may not want a milky one. |

Because I thought it was a problem! Others in air tight containers have none? I just got in some air tight for these, and was about to ask if they needed an acetone dip, but now?

I see toning and fingerprint marks. Some collectors like toning especially if it's colored like blue hues, etc. Your eagles are valuable for their silver but not collectable value in my opinion. Many collectors only hold their coins by the edge or use gloves and put them in capsules or tubes to protect them. There are Youtube videos on how to clean silver coins but be careful you might make them worse. If they were mine I would not clean them. Milk spots are caused at the mint and can show up later even if in capsules/tubes.

I was about to ask about the difference in the milky, but my original concern was the dark parts on the rim, maybe cpl faint ones in center

Are the plastic envelopes really soft and bend easily?

Silver is fairly reactive, so variable temperatures in combination with high humidity and contaminants in the air or the envelopes they are stored in can cause a silver coin to tarnish in various ways. While I do see discoloration due to fingerprints on at least one coin image, the other toning is likely a result of the environment and holders they were stored in.
Milk spots can develop on silver coins even in sealed holders, however. I've had a few proof sets purchased from the mint which have been kept in a carefully controlled environment since they were purchased in which the silver coins developed milk spots.
I wouldn't think acetone would help on any of these issues, but there's no harm in trying. Just be sure to use a glass dish and 100% acetone from the hardware store - never use fingernail polish remover, as it contains other chemicals than just acetone.
Since they're just bullion coins I wouldn't worry too much about it. However, over the years I have occasionally used a chemical dip to remove unattractive heavy tarnish from silver eagles that I have acquired, but that's something that should be done with great caution as you can easily make the coin look worse or even damage it if the dipping process is not done correctly and precisely. Again, on these, I'd probably leave them as-is.

Milk spots will not come off without damaging the coin. Acetone will not remove toning. Fingerprints are forever unless you remove them immediately, like within a few hours of putting them on the coin. John1  |

I didn't shoot a pic of the envelope, you thinking this could be a result of bad plastic in protector? I may have thrown the one that split in half away! I'll look when I get home this afternoon

this is the type of toning I see with plastic flips at the top where the pocket and fold is, the coin tones there quickly.
Acetone will not remove toning. this is one of the reasons I switched to 2x2s and capsules. 2x2s are fine unless there'sa pinhole in the mylar. that and every time I open a flip it cracks and I break it.
the 2x2 plastic flips are fine (the brittle ones) for smaller coins but morgans and ASEs take up most of the flip and theres an edge that sits exposed to the air. that tones faster than the rest.
usually dark and ugly also.
