Salt and vinegar create a patina on pennies primarily due to the acetic acid in vinegar and the sodium chloride in salt, which facilitate a chemical reaction. When pennies, primarily made of copper, are exposed to this mixture, it accelerates the oxidation process, resulting in the formation of copper salts and other compounds that give the pennies a greenish or tarnished appearance. This reaction is a form of corrosion that can enhance the aesthetic appeal of the coins for collectors or artists.
