When copper turns green-blue, that means the copper was oxidized by oxygen and chlorine (often found in salt). This oxidation reaction creates a different compound called malachite, which is green-blue in color. Keep the acid solutions that the pennies were soaking in to create copper coated nails.

That source of hydrocarbons seeps up through the earth's layers and slowly replenishes oil sources. What does oil do in the earth?
