with all that green on it (corrosion), it's not worth anything more than one cent.

The value of a copper penny from 1920 in good condition with some green corrosion (85-93% turning green) would likely be around 5 to 10 cents for its copper content. The coin's numismatic value might be lower due to the corrosion, unless it is a rare or highly sought-after variety.

Is the penny turning green like the statue of liberty turning green?
No, the green color on a penny comes from oxidation of the copper in the coin, while the Statue of Liberty turned green due to the natural weathering of the copper material it is made of over time. Different mechanisms are at play in these two situations.
Is copper turning green when exposed to the environment a chemical change?
Chemical because it is being exposed to another compound and forming a new substance
How fast will a penny turn green?
A penny can turn green due to the oxidation process when exposed to air and moisture. The speed of this process can vary depending on the conditions it is exposed to, such as humidity level and presence of other chemicals. In general, it can take several weeks to several months for a penny to turn green.
What will happen when iron and iron react?
Copper sulphate is a blue coloured solution. As soon as you react it with iron, you will notice that the solution is turning into light green which means iron sulphate solution is forming. Iron being more reactive than copper displaces copper from its soluion.
How can you tell that a chemical reaction occurred from the copper sulfate?
You can tell that a chemical reaction occurred with copper sulfate if there is a visible color change in the solution, such as the solution turning blue or green. Additionally, if there is a formation of a solid precipitate, like copper hydroxide forming as a blue-green solid at the bottom of the solution, it indicates a chemical reaction has taken place.
When Iron is turning into rust and copper turning green is an example of what kind of erosion?
"chemical"
What is the word for copper turning green?
The word is "oxidation", which in the case of copper is a three-step process where the copper oxidizes to copper oxide, then to cuprous or cupric sulfide, and then to copper carbonate. Copper carbonate is the green colored copper or patina that forms over time. The old name for this green patina is "verdigris".

Is copper turning green in the air physical change?
The reason that copper turns green is the same reason the metal rusts, oxidization. Both metal and copper oxidize when exposed to oxygen and this is a natural process. Copper that is exposed to the outside environment is more likely to turn green and that is why copper vases and decorative pieces in gardens are often green. Copper is a metal that does not react with water (H2O), but the oxygen of the air will react slowly at room temperature to form a layer of brown-black copper oxide on copper metal which looks like green sometimes...
Is turning of copper into green when exposed into environment physical or chemical change?
It is a chemical change.
Is copper turning green when expose to environment a chemical change and why?
Yes, the green patina that forms on copper is a chemical change called oxidation. When copper reacts with oxygen and moisture in the air, it forms copper oxide and then copper carbonate, creating the green color seen on aged copper surfaces.
Why is your skin turning green?

Your skin has many chemicals in sweat that attack the copper bands and allow them to corrode and oxudize turning the resulting chemicals green on your hand. You can also notice this action on copper wires that are exposed to the outside elements.
Why does copper turn black when it meets oxygen?
Copper turns black when it reacts with oxygen because it forms copper oxide on its surface. This copper oxide layer is black in color, giving the appearance of the copper turning black.
