If you’ve come across a piece of silverware marked “International Silver Co.” or “International Sterling,” you may be wondering what that name signifies — and whether the piece in question is genuine sterling silver or something else entirely.
The International Silver Company holds a significant place in the history of American silver manufacturing, and their sterling silver products remain sought after by collectors and enthusiasts alike. Here's what you need to know about this influential brand and the silver it produced.
The International Silver Company was established in 1898 as a consolidation of several prominent silver manufacturers based in Meriden, Connecticut. These included companies like Rogers & Brothers, Holmes & Edwards, and Meriden Britannia — all of which had built reputations in the late 19th century for quality silverware, both sterling and plated.
This merger allowed the new company to centralize production while continuing to use many of the original brand names. Over time, “International Silver Co.” became the overarching label for both high-end sterling lines and mass-market silver-plated products.
The company grew rapidly in the early 20th century, becoming a dominant force in the American silver industry and a household name in flatware, tea services, and serving pieces.
When you see the term “International Sterling” stamped on a piece, it indicates that the item is solid sterling silver, composed of 92.5% pure silver and 7.5% copper or other metals for strength. This is the same standard used across the United States and other countries that recognize the sterling classification.
These marks were applied by the manufacturer and are reliable indicators of silver content. The word “Sterling” was not casually used — it had legal and consumer recognition, and misrepresenting it would have been a significant liability for a major company like International Silver.
Some common markings include:
If a piece carries any of these marks, and no indications of plating (like “IS,” “EPNS,” or “silver plate”), you’re looking at genuine sterling.
Because International Silver produced both sterling and silver-plated lines, it's important to understand the distinction when evaluating a piece.
Silver-plated items often bear the full company name but lack the word “Sterling.” These items were made with a thin layer of silver over a base metal — visually similar, but significantly less valuable than solid sterling.
Plated pieces may also include abbreviations like:
If the word “Sterling” is missing, always assume the item is plated unless confirmed otherwise.
International Silver produced a wide range of sterling patterns, many of which remain collectible today. Designs like “Prelude,” “Royal Danish,” “Spring Glory,” and “Minuet” combine Art Deco, Art Nouveau, and classical influences, appealing to a broad spectrum of buyers.
These patterns are especially popular among collectors looking to complete sets or match heirloom pieces. Because the company’s sterling lines were produced in high volumes during the mid-20th century, many pieces are still readily available — though rare patterns or specialty pieces can carry higher values.
International Sterling items typically hold solid market value due to their silver content, craftsmanship, and recognizable brand name. Even worn or mismatched pieces can retain melt value, while complete sets in good condition can sell for a premium — especially when housed in original boxes or chests.
The company’s reputation for quality, combined with its clear marking system, makes its sterling items relatively easy to identify and trust, both for seasoned collectors and casual buyers.
International Silver Company sterling silver represents a significant chapter in American silversmithing. When properly marked, these items are genuine sterling, crafted to a recognized standard and backed by one of the most established names in 20th-century silver production.
If you’ve inherited or discovered a piece stamped “International Sterling,” you’re looking at more than just a brand — you're holding a part of American silver history, backed by quality, tradition, and lasting appeal.
