Found in Missouri. Im assuming it's a civil war era button but I'm unable to identify the state. I thought it was a Maryland or new jersey button but the design is all wrong. Any help appreciated.
These two bullets are .65 in long, .4114 diameter. The one on the top is 144 grain, on the bottom 148 grain. Both have the form of a Lemat with the most salient difference being the curvature at the waist. Can anybody provide a positive identification?
