Nice! That's and early war eagle button, it has the earlier type back mark. It looks to have some gold gilt on it too. It may clean up a bit more with an ammonia bath. Good luck on the neighbors.
Nice button! Your effort continues to pay off.
Thanks, guys. That yard across the street is really inviting. The back yard is about 5 acres and backs up to a lake where, in addition to the huge civil war presence, there was a race track in the 1700's and 1800's.
