History

Rogers Mfg. Co., Holmes & Edwards and Wilcox Silver Plate. It became one of the largest silverware makers in the world and kept using many of its member companies' names and marks for decades. Sterling holloware continued until 1976, and its silverplated holloware line was sold to Oneida in 1981.

Dating clues

  • A piece marked with a member firm's name (1847 Rogers Bros., Meriden B. Co., Wm. Rogers, Holmes & Edwards, Wilcox) may still be International-era work, because International kept those brands going after 1898. Some marks add 'International S. Co.' or 'IS' next to the old name.
  • Other International trademarks listed by silvercollection.it include 1847 Rogers Bros., 1865 Wm. Rogers Mfg. Co., Amsilco, Embassy Silver Plate, Insico and Old Company Plate.

Other names on the marks

International Silver Co.; I.S. Co.; Insilco

Where sources disagree: Wikipedia says International stopped making silver in 1983; silvercollection.it says sterling holloware ended in 1976 and silverplated holloware was sold to Oneida in 1981. The start and end years of individual International marks are not given by these sources.

Marks help identify a maker and a date range, but they can’t prove a piece is genuine. Reproductions and later reissues can carry old marks. This entry isn’t an appraisal.
