S. Kirk & Sons is one of the oldest and most respected names in American silver, known for its detailed repoussé work and traditional craftsmanship. Founded in 1815 by Samuel Kirk in Baltimore, Maryland, the company became famous for introducing the repoussé technique to American silver, creating intricate floral and scroll patterns that became its signature style. Silver marks from S. Kirk & Sons vary over time but often include combinations like “S. Kirk & Son,” “S. Kirk & Sons,” “Sterling,” and occasionally pattern or purity numbers such as “925/1000.” These marks help date pieces and confirm authenticity. The firm produced a wide array of sterling silver items, from ornate tea sets and serving trays to flatware and presentation pieces. In 1979, the company merged with the Stieff Company, further preserving its legacy. Identifying S. Kirk & Sons silver marks allows collectors to trace the rich history, craftsmanship, and value of each piece.
