Wow! Antique-shop.com forums are in the big #1 spot on Google for the search term "antique shop forum", for 4 years running!Thanks to YOU.
From what I can tell from the marks it's silver plated and unfortunately they haven't held their value (unless it's something very spectacular and collectible). I have a cedar chest full of mostly silver plate and 95% of the value is it's family connection.Wait for others to chime in to see what their opinions are.
