You need to do some work on your pics,so the kind folk on CCF can look at your coins and effectively answer your questions. Try these for immediate results. 1. Spin your coin so it is facing the right way up (A lot of us have really old joints in the neck) 2. Concentrate on getting the coin in focus 3. Once you have taken it, you should be able to open it and use the phone or desktop program to edit the shot. Crop the picture so only the coin plus a small margin is visible. 4. Voila! I can't change the focus but here is your first obverse, rotated and cropped. It took about 1 to 2 minutes to change.  (The lighting doesn't help either. Make it brighter) If you are trying to compare a toned coin, put a 'normal' coin in the shot so we can see the difference. All good, keep posting! The Ox moves slowly, but the Earth is patient.

They can go off fairly quickly under carpet mats in a car,especially if there is a bit of moisture around.

When Cu-Ni darken like this it is possible that they have been subject to heat stress.
Heat them to red hot, then quench in cold water, and they turn completely black.

Heat them to red hot, then quench in cold water, and they turn completely black. Both fair points.  The Ox moves slowly, but the Earth is patient.

We don't have "mint rolls" of common circulation coins. We have "security company rolls"., which might or might not include coins that have come direct from the mint. These coins were from a "used coin" source like a bank, rather than the mint, as is evident when they're dated from 2019 and 2018, and you're presumably opening the roll in 2022. Strange toning on relatively new coins that shouldn't have had time to get toned yet, is unusual, but not valuable.
Don't say "infinitely" when you mean "very"; otherwise, you'll have no word left when you want to talk about something really infinite. - C. S. Lewis
