The image displays hallmarks on a silver-plated item, specifically indicating "SILVER ON COPPER" and featuring three distinct symbols within arched frames: a crown, an "S," and a shield. 

• "SILVER ON COPPER": This inscription indicates that the item is silver-plated, with a layer of silver applied over a copper base metal. 

• Crown, "S," and Shield: These three symbols together are identified as the hallmark for the Sheridan Silver Co., Inc., a company incorporated in Taunton, Massachusetts, in 1946.
