I will answer without photos since I am familiar with this set. Photos just help with accuracy, but are not absolutely necessary.
This is a silver plated (not sterling silver) five-piece tea service in the American Rose pattern made first by Wilcox of Meriden, Ct
and became part of the patterns offered after Wilcox was acquired by International Silver. If the bottom reads Webster-Wilcox, then the set dates to after 1961 when the additional company was acquired and added to the International Silver family. Your set, if marked Wilcox, dates to the 1920's to 1940's and the numbers on the bottom of the separate pieces should all be in the 7000 range( 7300-7392). These numbers represent each shape within the pattern.
Your five-piece set has a current value of $250 to $325 as long as there are no dents, wobble when sitting on a flat surface, and no monograms.
Deduct 10% each for any of those issues on the five pieces.
Some sites that I recommend for selling are Offerup.com (local), Varagesale.com (local) , Ioffer.com, Ebay and letgo.com (local).
You can also go to invaluable.com or liveauctioneers.com and search their directory for an auction house near you and consign to them.
