What are things that have copper in it.
Lots of wire are made from copper. Wires in your headphones are pretty easy to see if you want to take them apart. Or if they are frayed then you can probably see them. Pennies are made from copper and so is that statue of Liberty. Copper oxidizes over time and begins to turn a green colour from that. Other things with copper in it are Copper wire electromagnets circuit boards copper nails pipes/sinks and some ammunition has copper casings.
