Understanding the Difference
Sterling silver vs. silverplate: what you need to know
Most inherited silver falls into one of two categories: sterling silver or silverplate. The difference is fundamental. Sterling silver is a precious metal with intrinsic value. Silverplate is a thin coating of silver over a base metal. Knowing which you have is the single most important factor in understanding what your inherited silver is worth.
What is sterling silver
Sterling silver is an alloy of 92.5% pure silver and 7.5% copper. The copper is added for strength — pure silver is too soft for practical use. Because sterling is mostly silver by weight, it has real intrinsic metal value that rises and falls with the silver market. A heavy sterling tea set or a complete flatware service can be worth hundreds or thousands of dollars in silver content alone, before any consideration of craftsmanship, age, or maker.
Sterling is identified by specific marks. American sterling is typically marked "Sterling" or "925". British sterling carries the lion passant — a small image of a lion walking to the left — along with hallmarks indicating the city, date, and maker. French sterling is marked "950" (a slightly higher purity standard). If you see any of these marks, you have genuine silver.
What is silverplate
Silverplate is a base metal — typically copper, nickel, brass, or an alloy called nickel silver — coated with a very thin layer of silver through electroplating. The silver layer is measured in microns. It looks like silver on the surface but contains very little actual silver by weight. When the plating wears through, the base metal underneath becomes visible, often appearing as a coppery or yellowish color on edges and high-contact areas.
Silverplate marks are distinct from sterling marks. Common silverplate marks include "EP" (electroplate), "EPNS" (electroplated nickel silver), "EPC" (electroplated copper), "silverplate," "quadruple plate," and "A1" (a quality grade). Despite the word "silver" appearing in some of these terms, silverplate is not sterling silver and has minimal precious metal content.
How to check marks
Finding the mark is the fastest way to identify what you have. On flatware — forks, spoons, and knives — turn the piece over and look at the back of the handle. The mark is usually stamped near the top of the handle or just below where the handle meets the bowl or tines. On holloware — bowls, pitchers, platters, and trays — flip the piece over and check the underside or bottom. On tea sets and coffee pots, marks are typically on the bottom or near the base of each piece. On candlesticks, check the underside of the base.
Marks can be small, shallow, and worn from years of use and polishing. Use good light — natural daylight or a bright lamp at an angle — and a magnifying glass. Some marks are only legible under magnification. If a piece has no visible marks at all, it may be unmarked sterling, unmarked silverplate, or another metal entirely. A specialist can often determine the composition from photos of the piece and its wear patterns.
The ice test and magnet test
Two simple home tests can provide clues, though neither is definitive. Sterling silver is an exceptional conductor of heat. Place an ice cube on the surface of the piece — if it is sterling, the ice will begin melting almost immediately, noticeably faster than on other metals. This works because silver has the highest thermal conductivity of any common metal.
The magnet test is even simpler. Sterling silver is not magnetic. If a strong magnet (a refrigerator magnet is usually too weak — use a rare earth magnet) sticks to the piece, it is not sterling. However, silverplate over a non-magnetic base metal will also pass this test, so a piece that is not magnetic is not necessarily sterling. These tests are useful for quick screening but are no substitute for reading the marks or getting a professional opinion.
Coin silver
Coin silver is a third category that sometimes appears in inherited collections, particularly in older American estates. Coin silver has a purity of 900 parts per 1000 (90% pure silver), slightly lower than sterling's 925. It was the standard for American silver before the mid-1860s, when the sterling standard became dominant. The name comes from its origin: silversmiths literally melted down silver coins to make flatware, holloware, and other objects.
Coin silver is marked "coin," "C," "D" (for dollar), or "900." Pieces by known early American silversmiths can be quite valuable — both for their silver content and as antiques. Pre-Civil War American coin silver flatware and holloware by documented makers is actively collected and can command strong prices at auction.
When silverplate IS valuable
While most silverplate has limited resale value, there are exceptions worth noting. Early Sheffield plate — made before about 1840 by fusing a layer of silver to copper through heat and pressure rather than electroplating — is collectible in its own right. Sheffield plate predates the electroplating process and represents fine craftsmanship. Quality examples, particularly large holloware pieces, can sell for meaningful amounts.
Some silverplated holloware by quality makers retains value for decorative use — large serving trays, elaborate centerpieces, and well-designed tea services can sell to decorators and buyers who appreciate the form regardless of the metal content. Certain pieces by specific European makers are also collected, particularly ornate 19th-century holloware with strong design quality. But these are exceptions. The vast majority of inherited silverplate flatware has minimal resale value.
