Purchased a tray today. Wondering if it has value

Hi all!
I did read quite a few posts here before posting myself and I have come to the conclusion that American Silver Plated items aren’t worth much. However I have also found that Scheffield pieces may be worth something.

With that said I just wanted to see if anyone could date my tray by the markings.
I found them online and have attached a link to the site.
Under “wallace” it is the very last logo with the “WCNS”

Is it worth anything at all?
Thanks
Missy
