The Gorham Sterling & Other Metals E x A mark appears on mixed-metal pieces produced by the Gorham Manufacturing Company, known for pioneering this decorative style in the late 19th century. The phrase “Sterling & Other Metals” indicates that the piece is crafted from sterling silver combined with other metals—typically copper, bronze, or gold—for artistic contrast, especially in Aesthetic Movement designs. The marking “E x A” is likely a workshop code or artisan’s initials used to track production or design attribution. These mixed-metal pieces are rare and highly collectible, reflecting Gorham’s most experimental and creative era.
