Tiffany and Company Inc of New York began producing its own sterling flatware in the late 1800's, but as early as the 1850's had sold the wares of other makers that bore its name. The company introduced the English sterling silver standard (925/1000) in the United States in 1852, and this was later adopted as federal law to determine sterling silver purity.
