Please Read Before Posting A Topic

In the title please put date, denomination and type of coin design and a brief on what you are asking about.
In example: "1995 Lincoln Cent Missing 5" or "2010 Roosevelt Dime With a Line inside the rim".

All of this helps discern the different topics from each other and is much less confusing to members who want to help.
Topic titles like "how did this happen" or "help" often get ignored and lost in the confusion.

Also if you're having trouble posting an image then here's our guide for that. How To Post Images

The green you are seeing is call Verdigris.
 Verdigris Definition:
   1. a. a green or greenish blue poisonous pigment resulting from the action of acetic
         acid on copper, consisting of one or more basic copper acetates, and formerly
         used in medicine 

      b. normal copper acetate

   2.    a green or bluish deposit especially of copper carbonates formed on copper,
         brass, or bronze surfaces

Acetone (must be pure) will remove verdigris. A quick soak is normally all it takes. No need to rinse as the acetone will COMPLETELY evaporate off of the coin.

I've gotten the same advise from Dan and Earle; for me it depended on the metal. I had ones worse than yours and had good results. But.....I've only did a few and they weren't great coins to begin with. More of a trial run I guess.

I don't think I'll ever be in the habit of cleaning coins.

If acetone fails, then xylene. One is polar solvent and one is non-polar. Meaning one can take of things the other does not.
I don't think I'll ever be in the habit of cleaning coins.
I know it seems to be splitting hairs, but using these two chemicals on a coin is not what the hobby typically means when the word "cleaning" is used . The word cleaning usually means something that alters (destroys value) the coin's metal.

If someone spilled Pepsi on a coin, they would be smart to rinse it off. This is not "cleaning" the coin since it is removing the surface Pepsi and not changing the metal in any way. So this action is called conserving.

Now if someone used a wire brush or some corrosive acid to remove the Pepsi, therefore damaging the coin's metal also, then they have "cleaned" the coin.
