American Civil War era Minié ball style bullet used in muzzle-loaded rifled muskets. The object is made of lead and conical in shape with the tri-ring grooves and recessed bottom that are the standard for the type; the recess is an intentional design used to cause the most damage possible when firing. There are a few nicks and scratches on the surface of the object, but what is most notable is the strange coloration/patina, the bullet is almost completely covered with a bronze color which is shiny in its look, this is abnormal as lead is naturally dulled to gray after cooling due to exposure to oxygen, then further dulled over time by the white patina that is most often caused by exposure to carbon dioxide, it is very uncommon to see a lead object that is this color or reflective/shiny in appearance.
