How is Stieff Sterling 1918 Hallmark identified?

The Stieff Sterling 1918 Hallmark features the distinctive triangle (or pyramid) date mark, which The Stieff Company used to identify silver produced specifically in 1918. This geometric symbol predates the later alphabetical date-marking system and is part of Stieff’s early hallmark catalog, used during a period when the company was expanding its workshop and refining its die-struck sterling techniques. On most pieces, the triangle date mark appears alongside the traditional “STIEFF STERLING” stamp, sometimes accompanied by a pattern number. Silver from 1918 often shows early Stieff characteristics—crisp detailing, deep strikes, and substantial weight—reflecting the company’s reputation during the World War I era for producing durable, high-quality sterling. Because early symbol-based date codes were used for a limited span of years, triangle-marked 1918 Stieff pieces are of particular interest to collectors, providing clear, verifiable dating for antique Stieff silver.
