WM Rogers 5 pc Tea Set

I have a 5 peice WM Rogers Tea set. I have been told it is silver plated. I am not exactly sure if it plated or not. Their is a marking on the bottom that says, "WM Rogers" Their is a strange logo in front of the WM, it looks like a bird. Then at the end their is a star.

I am trying to find out the year it was made, what exactly it is made out of, and a price?

Thank You

Matt
