Rogers Brothers silver marked "IS" typically indicates that the piece was manufactured by the Rogers Brothers Silver Company. The "IS" stands for International Silver, which was a brand and division of the Rogers Brothers Silver Company. The Rogers Brothers Silver Company was a well-known American silverware manufacturer that operated from the mid-19th century to the early 20th century. The company was known for producing high-quality silver-plated flatware, hollowware, and serving pieces.
If you have a piece of silver marked "IS" from Rogers Brothers, it is likely silver-plated rather than solid silver. Silver-plated items have a thin layer of silver coating over a base metal, such as copper or brass. The marking "IS" along with the Rogers Brothers name is a common hallmark found on their silver-plated products.
Even without being sterling, pcs are valued at $3-$4 dollars each due to the weight of the metal
