These alphanumeric or symbolic inscriptions are found on items produced by the Wrttembergische Metallwarenfabrik (WMF) that have been coated with a layer of silver through electroplating. These are distinct from hallmarks on solid silver, which guarantee precious metal content. An example would be WMF 90, where “90” indicates the grams of silver used to plate a specific surface area of base metal, typically brass or copper.
The presence of these stamps is crucial for identifying the manufacturer and quality level of the silverware. They provide insights into the age and origins of the object, allowing collectors and researchers to trace its provenance and understand its historical context. Understanding the numbering system denotes the thickness of the silver layer, thereby informing its durability and value. It also facilitates accurate appraisal and authentication, differentiating it from solid silver items or pieces from other manufacturers.
