It's easy! Pennies were never made of silver. They would be worth way more than a cent. Steel pennies were made in 1943. So if you have a penny that was minted in 1943 it's not silver but rather steel.
If it was minted in 1981 or before [except for 1943 which were made from steel] it is bronze. In 1982 some were made of bronze and some were made of copper clad zinc. The copper clad zinc cents are lighter than the bronze cents. You can weigh them to tell the difference. Also, if you drop them on a hard surface, the bronze cent will have a greater metallic ring to it than the zinc cent. Bronze cents look a little different in color too. While not a foolproof way to tell, most seem to have a slightly darker appearance than the zinc cents. This is because the plating on the zinc cents is pure copper and the bronze cents are not pure copper and thus have a slight difference in color usually.
