Wilcox International Silver CO. Serving Tray

I have a WILCOX  International Silver CO. Joanne piece that I purchased from a Goodwill store and am very interested to find out more about this piece and what it is worth. I may decide to sell it. Not sure.

The piece is stamped with no trade mark, but is is stamped with the words WILCOX Under that is the blocks I S. Under that is International Silver CO. Then is is inscribed with the word Joanne. No other markings appear.

The piece is footed with a design around the outside edge. The piece is tarnished and has a few minor scratches.

Looking for this on the internet, I found a similar piece on another web site, but it was slightly different.

1. The other piece identification said WEBSTER WILCOX. My piece doe not say that. It says WILCOX only.

2. The other piece was also slightly smaller in width. The other piece was 11 inches, and mine is 13.75 inches But same design and footing.
