The process of silver plating is done by electroplating a thin layer of silver over a stronger and usually less expensive base metal. Quadruple silver plate contains 8 troy ounces of silver, compared to standard silver plate, which contains just 2 troy ounces. With its silver finish, improved durability and pricing that was more affordable than pure silver pieces, quadruple silver plate soared in popularity during the late 19th century, according to Abe Silverman of Abe Silverman's Antique Silver Shop. Many of these same high-quality quadruple silver plate items are still in circulation today. With a little effort, you can enjoy your quadruple silver plate pieces for many years.
