No.
Only if they have pmd or machine doubling
Worth .25 cents

just common everyday quarters that looked exposed to heat, or something else, not worth anything but 25 cents

By and large, the stuff you are looking at is just too modern and too common to matter.
Lots of people would NOT consider this toning. It is "damage".
I personally like MS coins. Coins don't come from the mint toned.
If one of them ends up looking like Jesus, you may get lucky
No.
Generally toning on modern coins is meaningless since the process of toning takes years to progress. If after years you have 3 or 4 distinct colors present, you may have value. If you have just one or 2 colors the coin needs to have exceptional eye appeal. The key is colors. brown doesn't get anyone worked up.
That discoloration looks more like residue or reaction to something that was deposited on the surface.... Acetone will likely remove it - if it were tarnish, acetone would not affect it. Further, that nasty brown/black staining is not attractive... and even if on an old coin, would not attract a premium. Cheers, RickO
Better fothos I looks like no damage or heat or acid I am not an spert just learning?
