How many copper pennies are in a one-cent coin?
Excuse me, but I'm a bit confused by your question. Are you asking about the composition of a modern one-cent coin, specifically in relation to copper pennies? It's important to note that the composition of the penny has changed over time. For instance, in the United States, the penny was originally made of pure copper, but starting in 1982, it was changed to a zinc CORE plated with copper. So, to answer your question directly, a modern one-cent coin in the United States does not contain any copper pennies within it. It's simply a zinc core with a copper plating. Is there something else you'd like to know about the penny or its composition?
