The photo above shows four coins (middle row and bottom center and right), a bottle cap (bottom left), a button of some sort (top left) and several pieces of ammunition. The musket ball (upper right) is made of lead. Musket balls were used for hunting and war, but haven't been commonly used since the 1800's. While metal detecting, my son has now found three. To clean them he lets them sit in a bowl of vinegar. They are heavy and by holding them he learned a bit more about science and materials.
There are many educational benefits in encouraging kids in there interests. Passion often motivates children and adults to read, research and experiment.
