Look to see if the mark on the back of any of the pieces says STERLING or has the number 925. If not, then your set would be silver plate (not sterling). International/Rogers made the Joan of Arc pattern (designed circa 1940) in both sterling and silver plate. A 46-piece set in sterling has a value of $1750 and a 46-piece set in silver plate has a value of $125 to $175.00.
Some sites that I recommend for selling are Varagesale.com, Ioffer.com, OfferUp.com, Ebay and letgo.com.You can also go to invaluable.com or liveauctioneers.com and search their directory for an auction house near you and consign to them.
