I bought this curious button at the flea market this morning. It appears ground dug to me. The back is magnetic but and is badly corroded. The front is not magnetic and I suspect it is brass. The button is 7/8 inches across. There are 24 stars around the border.
At first I thought this might be an ensign's uniform button but those that I have seen do not have the stars around the border.
Any thoughts on this one?
