If your pool is properly water balanced and has a pH near 7.5 (certainly greater than 7.2), then it is unlikely that the copper pennies will be a problem with either water balance or stains. Remember that the heat exchanger in a gas pool heater is probably copper and water flows through it whenever the pump is running (even when the heater is turned off). Also, consider that many homes use copper water pipes.
Metals will corrode (oxidize) in acidic conditions with the presence of dissolved oxygen though the actual factors are quite complex. Nevertheless, you should probably scoop out the pennies from the pool after your kids have had their fun, mostly for safety and aesthetic reasons.
Too many pennies(say a gallon of them or so) may cause green water if improper water balance but copper is a natural germ killer so no it can only be a benefit unless they get into your pump.
ANSWER::
Remember that water is a solvent and can dissolve many things. Even if you have a "perfectly balanced" pool ( and realistically nobody does) those pennies will stain the pool -- they are not solid copper and have a mixture of other elements in them.

Chlorine is more reactive than bromine. This is because chlorine has a higher electronegativity and smaller atomic size than bromine, allowing it to more readily undergo chemical reactions.
Chlorine can be separated from water by allowing the water to sit for a period of time, as chlorine will naturally evaporate. Alternatively, chlorine can be removed by using activated carbon filters or chemical treatment methods such as sodium metabisulfite.
the most likely culprite is chemical or biological chlorine uptake. something in your water isn't allowing you to achieve break point chlorination ( the point at which you can measure free chlorine). This could be due to ammonia, sulfur, iron deposits or some other chemical in your sourcewater that is "eating up" your chlorine.
The chemical formula for ammonia is NH3, and the chemical formula for chlorine is Cl2.
The Chemical formula of chlorine dioxide is CIO2.
The chemical formula for carbon and chlorine is CCl4 (carbon tetrachloride).
The chemical formula for chlorine is Cl. When two chlorine atoms combine, they form a diatomic molecule, so the chemical formula for two chlorine atoms combined is Cl2.
No. Chlorine is a chemical element.
Chlorine is "CL".
Chlorine is a chemical element.
The chemical formula for chlorine oxide is Cl2O.
The chemical formula for chlorine is Cl, which represents one atom of chlorine. C1 is not a valid chemical formula.
