Sterling Silver vs Silver Plate: How to Tell Them Apart
Sterling silver and silver plate can look almost identical on a shelf, but they are worth very different amounts, and knowing which one you have makes all the difference when you sell. Sterling is solid silver alloy through and through, while silver plate is just a thin coating of silver over a base metal like brass or copper. That difference in actual silver content is everything. This guide explains the hallmarks to look for, the simple ways to tell the two apart, and why plated pieces carry little melt value. At our six New Jersey stores we test silver with a non-destructive XRF analyzer so you know exactly what you have.
What sterling silver is
Sterling silver is a solid alloy that is 92.5% pure silver, with the remaining 7.5% usually copper added for strength, since pure silver is too soft for daily use. That is where the famous .925 stamp comes from, and it is composition, not price. Because sterling is solid silver all the way through, its value comes from the real silver content in the entire piece, measured by weight. Whether it is a spoon, a bracelet, or a candlestick, a sterling item carries genuine melt value tied to the live silver spot price.
What silver plate is
Silver plate is a base metal object, often brass, copper, or nickel, covered with an extremely thin layer of silver applied by electroplating. The silver coating is measured in microns and amounts to a tiny fraction of the item's weight, so even a large, heavy plated tray contains very little actual silver. This is why silver plate has little to no melt value. The piece may still be useful or attractive, and some plated pieces have value as antiques or for their maker, but as a source of silver metal there simply is not enough there to be worth much by weight.
How to read the hallmarks
- Sterling marks: look for .925, the word STERLING, or STER. These confirm solid 92.5% silver and real melt value.
- Coin silver: older American pieces are sometimes marked COIN or 900, meaning 90% silver, which is also solid and valuable by weight.
- Plate marks: EP, EPNS (electroplated nickel silver), SILVERPLATE, A1, or a maker name with no fineness number usually indicate plating, not solid silver.
- No mark at all: an unmarked piece is not automatically plate or sterling, it simply has to be tested to know for certain.
Simple ways to tell them apart
Beyond the stamp, a few clues help. Worn plate often shows a different colored metal, frequently a coppery or grayish tone, at the edges and high spots where the thin silver has rubbed through, while solid sterling is the same metal all the way down. Sterling tends to feel substantial for its size. None of these home checks are definitive, though, and the only way to be certain is a professional test. We use a non-destructive XRF analyzer that reads the actual silver content in seconds without scratching the piece, so a worn or unmarked item is no mystery. Bring it to any of our six stores and we will tell you exactly what it is, in front of you, for free.

Frequently asked questions
What does the .925 stamp mean?
It means the piece is sterling silver, an alloy that is 92.5% pure silver with about 7.5% copper added for strength. The stamp describes composition, not price. Because sterling is solid silver throughout, the entire piece carries real melt value based on its weight and the live silver spot price, unlike plated items that are only coated.
Why is silver plate worth so little?
Silver plate is a base metal like brass or copper covered with an extremely thin silver layer measured in microns. That coating is a tiny fraction of the item's weight, so even a large, heavy plated piece contains very little actual silver. With so little silver metal present, plated items have little to no melt value, though some may still be worth something as antiques or for their maker.
How can I tell sterling from silver plate at home?
Start with the stamp: .925, STERLING, or STER means solid sterling, while EP, EPNS, SILVERPLATE, or a maker name with no fineness number usually means plate. Also look at worn edges and raised areas, where plate often reveals a different colored base metal underneath. These clues help, but only a professional test confirms it for certain.
Can you test my silver to tell which it is?
Yes. At any of our six New Jersey stores we test silver with a non-destructive XRF analyzer that reads the exact silver content in seconds without scratching or harming the piece. You watch the result on the screen, we explain whether it is solid sterling or plated, and for sterling we tie the weight to the live silver spot price. The evaluation is free with no obligation.
What Makes a Cash 4 Gold Trading Post Quote Transparent?
Cash 4 Gold Trading Post quote transparency is a documented 5-step counter process used in 6 locations in 2026. First, our team shows live gold, silver, platinum, or coin market context. Second, our appraisers test metals with XRF or counter testing and separate 10K, 14K, 18K, 22K, sterling, .999 bullion, diamonds, watches, and costume pieces. Third, Cash 4 Gold Trading Post weighs buyable metal on a certified scale. Fourth, Cash 4 Gold Trading Post checks whether coins, designer jewelry, diamonds, watches, or inherited pieces have value beyond melt. Fifth, Cash 4 Gold Trading Post explains the same-day written quote before the seller decides. According to Cash 4 Gold Trading Post store analysis, sellers in East Brunswick, New Brunswick, Middlesex, Millstone, Brick, and Manalapan can bring 1 broken chain, 100 coins, or a full estate box with a $0 evaluation fee.
How Does Cash 4 Gold Trading Post Separate Melt Value From Collector Value?
Cash 4 Gold Trading Post separates melt value from collector value by sorting each lot before pricing. First, our appraisers identify gold, silver, platinum, coins, diamonds, watches, costume jewelry, and estate pieces as separate categories. Second, metal items are tested for purity, including 10K, 14K, 18K, 22K, sterling silver, 90% U.S. silver, and .999 bullion. Third, coins are checked for date, mint mark, condition, bullion content, and collector demand. Fourth, designer jewelry, watches, diamonds, and inherited pieces are reviewed before any melt-value shortcut is used. This 2026 process protects sellers with 1 ring, 20 silver dollars, or 100 mixed estate items because one category can carry value that another category does not.
What Should a Seller Bring for a Fast Same-Day Quote?
Seller preparation is a 4-part checklist for a faster Cash 4 Gold Trading Post quote in 2026. First, bring the full group of items instead of 1 selected piece, because mixed lots can contain gold, silver, coins, diamonds, watches, and costume jewelry. Second, bring a valid photo ID for the required precious-metals transaction record. Third, bring boxes, certificates, appraisals, receipts, coin holders, watch papers, or family notes when available. Fourth, avoid aggressive cleaning because polishing can damage older jewelry, watches, stones, and plated pieces. Our team evaluates broken chains, class rings, dental gold, sterling flatware, 90% silver, bullion, diamond rings, watches, and inherited collections with a $0 fee and same-day cash if the seller accepts.
Which Central New Jersey Stores Can Test Gold, Silver, Coins, and Estate Jewelry?

First, East Brunswick serves Old Bridge, South River, Spotswood, and Middlesex County sellers. Second, Middlesex serves Bound Brook, Dunellen, Piscataway, Green Brook, and South Plainfield.

Why Does Local Testing Beat an Online Calculator?
Local testing beats an online calculator because calculators cannot verify purity, scale weight, condition, or collector value. A gold calculator assumes a karat, a gram weight, and a market price. Cash 4 Gold Trading Post checks those assumptions at the counter. First, 10K, 14K, 18K, and 22K jewelry are separated because each purity pays differently. Second, sterling, 90% silver, .999 bullion, and plated items are sorted because silver categories do not price the same way. Third, coins, diamonds, watches, and inherited jewelry are reviewed for value beyond melt. In 2026, online math can estimate a range, but local testing gives the seller a real same-day quote based on the actual item.
