  For most of them, yes. But if you get old enough pennies, they’ll be pure copper.

  However, it’s easy to tell just looking at this that many of these pennies have the newer design, so they’re definitely only copper plated.

    Piss on em. Real copper will turn light green.

    You’re welcome.

      They’re all real copper on the outside. Even the fake ones are copper plated. So the surface you’re pissing on is copper regardless.

      If you want a simple way to find pure-copper pennies, you don’t need piss – just look at the dates on them. Dates before 1982 will be pure copper (with a few rare exceptions), and after 1982 are pretty much all copper-plated zinc.

        Sounds like something a person who doesn’t want to piss several times on his pennies would say.

  Brass?

    Brass is an alloy where the two metals are melted together, the pennies are a zinc core with a thin copper coating. Think of the former as a chocolate/vanilla swirl and the latter as a vanilla cone dipped in chocolate but ya know, with chemistry magic going on
