I have 5 pieces of antique sterling. They are marker sterling = .925 silver.
Then I have 15 pieces of flatware, spoons, forks, knives.
I see silver plated on some, only brand names on others like Wm. Rogers and Sons, H&T Mfg., Rogers and Bro., Vernon, E.E. & S.C. Bailey, etc.
How much silver is in silver plated?
How to tell about the ones that are not marked as silver plated?
