The Tiffany 711 mark is stamped on sterling silver pieces made by Tiffany & Co., one of the most renowned names in American silver. This mark typically includes “Tiffany & Co.” along with the pattern or design number “711,” which is used to identify a specific item in the company’s extensive silver catalog. The presence of this number helps confirm authenticity and provides a reference for dating and evaluating the piece. Tiffany’s pattern numbers are essential tools for collectors and appraisers, especially when tracking earlier or discontinued designs. A piece marked Tiffany 711 reflects the brand’s hallmark quality, elegance, and collectible value.
