Great Button. What is it?

[coinsareawesome]

I have this button that I bartered for from my buddy. He told me that it is a Civil War Navy button, but is there any value for these kinds of things? Please let me know.

That is a Marine Corps button

Thank you! Any idea on value?

First, is this button a 1-piece, or 2-piece. Also, what are the back-marks (the words on the back)

 

[coinsareawesome]

I can see lettering, but I can't make out what it says

 

[gsxraddict]

take a clear picture of the back

I tried at least nine different pictures and this is the best one I took.

Waterbury, I can't make out more of it. Possibly post civil war?
