I dug this up with a Bullseye canteen a couple of years ago in the mountains of North Carolina near a monument about the last shots fired in the war located in Waynesville NC and have been using it as a paperweight. I think it might be a Civil War Lead Shot ingot. It measures 4 in by 2 in by 1.5 in and weighs 1 lb 8.4 oz. Non magnetic.
