Civil War buttons? But are they the real deal?

I found these two buttons in Michie, TN today. There was an Civil War re-enactmemt nearby so I'm thinking that these two buttons came off an re-enactment soldier a few years ago. I have my doubts about these buttons being the real deal. If anyone has any input that would be great. The backmarks on the buttons have which looks like an N in a shield.

Also , the front of the buttons have the word " Excelsior " written on it.
