The Gorham Sterling A4070 mark is stamped on sterling silver items manufactured by the Gorham Company, a historic American silversmith known for precision and elegance. This mark includes “Gorham,” “Sterling,” and the model number “A4070,” which designates a specific pattern or form within Gorham’s catalog. The “A” prefix often refers to a particular design series, helping further narrow down the production period and stylistic details of the piece. Items with this mark are typically hollowware and reflect Gorham’s high standard of craftsmanship. The A4070 mark is an important identifier for collectors and appraisers to confirm authenticity, origin, and catalog context.
