Yes, William Rogers silverware is typically made from sterling silver, which is composed of 92.5% silver and 7.5% other metals. However, some pieces may be silver-plated rather than solid sterling. To confirm if a specific item is sterling silver, look for the "925" or "sterling" mark on the piece. If it only has a "Wm. Rogers" mark, it may be silver-plated instead.

1847 Rogers Bros IS 9041, known as the "Her Majesty" pattern, is made of silver plate, not sterling silver. The "IS" stands for "International Silver," indicating it is a silver-plated product rather than solid sterling silver, which is typically marked with "925" or "sterling." Silver plate items are generally less valuable than their sterling counterparts.
