Wm. [William] A. Rogers is an American company that manufactured silverplate almost exclusively. American companies are going to have a stamp on the back that says "sterling" or "925" if it's sterling silver. If it doesn't say sterling or 925, it isn't sterling. It's possible that an item manufactured before the Civil War (pre 1861) may not bear a sterling mark, but that's an extremely rare circumstance. Very little pre-Civil War sterling still exists and the chances of finding a piece floating around is infinitesimally small. Just to mention, many companies included the word "silver" in their name; seeing an item with the word silver stamped on it doesn't mean that the item is sterling. Many people make that mistake.
Nickel silver is a metal alloy that is made of copper, zinc, and nickel. No silver. However, it can be polished to a beautiful shine. Wm. A. Rogers manufactured some nickel silver flatware; you might be able to put together a set of flatware if you wish. It may take some hunting, however. They didn't manufacture much in that line, but since it's very durable and useless for silver smelting, it still exists. I just saw a set of iced tea spoons that tempts me.
I am from goa and have a tea spoon on which it’s written M & W unplated is it of silver? Because internet says unplated can be silver Sometimes, please help me out.
Yes I can buy. But. You may not like the price I will be willing to pay you. Please keep in mind that most of the stuff I buy I will pay 30 to 60 percent of the melt value. Are you looking to sell it for cents on the dollar?
