Pic doesn't show it but the outline area of Lincoln memorial has along with most of lettering has a greenish tint covering them. Obverse has it on MM and not sure if you can see in the word GOD has a faint doubled image but that isn't greenish. Signed Confused with a headache...
Take Advil or Tylenol Looks like split plating issue on the reverse exposing the inner zinc. The D mint mark has very clear split plating! And normal toning on the Obverse. Nothing major.
You're seeing things that are there but are not errors. Stop looking for anomalies that aren't errors. Chris
That's just a normal slightly circulated cent. Any 'color' you might see is due to circulation, although I don't see anything greenish on it.
Go with all three of the above answers. Start with something for your headache and realize that any green you see that the camera will not pick up may be toning starting to form from contact with the environment. Remember, it's zinc.
