International Silver Company is a major name in American silver, known for producing both sterling and silver-plated items with wide appeal. Formed in 1898 through the merger of several New England silversmiths, the company became one of the largest silver manufacturers in the United States. International Silver marks can vary but often include the company name, “Sterling” for solid silver items, and pattern names or numbers. Some pieces may also reflect the mark of the original silversmithing firm that became part of the International Silver umbrella. The company is well known for elegant flatware patterns, serving pieces, and decorative items that were staples in American households throughout the 20th century. Collectors value older sterling pieces for their design, quality, and historical relevance. Identifying International Silver marks is essential for dating and valuing a piece, whether it is an heirloom or a vintage market treasure.
