You're at an estate sale and a box of old flatware is sitting on a table with an $8 price tag. Or you've pulled out your grandmother's silverware set and wondered what it's actually worth. The short answer is: if it's sterling silver, a lot more than most people think. Silver is trading around $76 an ounce right now, up from under $34 a year ago. A typical 48-piece sterling flatware set contains roughly 80 troy ounces of silver. Do the math and you're looking at $4,800 in raw silver value before a buyer takes their cut.
The problem is that sterling and silver-plated flatware look nearly identical. Both tarnish. Both polish up beautifully. Both feel like silverware. But one contains real silver and one is a thin coating over cheap base metal. Most silver buyers won't touch the plated stuff. The difference in payout can be thousands of dollars.
Here are the most reliable ways to know which one you have, starting with the fastest and working toward the more definitive.
Check the back of the handle first
Turn a piece over and look at the back of the handle, near where it meets the tines or bowl. That's where sterling silver hallmarks are stamped. The marks are small, sometimes worn, and easy to miss if you don't know where to look. Wipe the area with a soft cloth first so you're not reading through decades of tarnish.
On American flatware, you're looking for the word “Sterling” or “Ster,” or the number “925” (which refers to the 92.5% silver content). On older British pieces, the mark is often a lion passant, a small image of a walking lion. There may also be a letter indicating the year of assay and a symbol for the city where the piece was tested. You don't need to decode all of those to confirm you have sterling. Finding any recognized purity mark is enough to start.
Some very old pieces have marks that have partially worn away after generations of polishing. If you can't read a mark clearly, try breathing on the metal the way you'd fog a window. The condensation can make faint stamps visible. If the marks are still unclear, a local jeweler can confirm with a quick look, often at no charge.
Look for the stamps that tell you it's not sterling
Just as important as knowing what sterling looks like is knowing what plate looks like. EPNS stands for electroplated nickel silver, which sounds official but means there is no solid silver in the piece at all. Just a thin coating over a nickel alloy base. You'll also see EP, EPBM (electroplated Britannia metal), or just a plain A1 quality mark. Any of those abbreviations mean you have plate.
One thing that trips people up is that plated flatware manufacturers deliberately designed their marks to look like real hallmarks. They stamped multiple small symbols in a row, similar to how official British assay marks appear. At a glance, they can look authoritative. Look closely. If the string of symbols contains EP or EPNS anywhere, it's plate regardless of how impressive the mark looks overall.
A word on the “IS” mark: that stands for International Silver Company, a large American manufacturer that made both sterling and plated lines. The IS mark alone doesn't tell you anything about silver content. You need to see “Sterling” or “925” alongside it to confirm the piece is solid silver.
Run a magnet over it
Sterling silver is not magnetic at all. Take a strong magnet, a neodymium magnet works best, though a decent fridge magnet will do for a first pass, and hold it against the flatware. If the piece pulls toward the magnet or sticks, it is not sterling. You can stop there. The base metal underneath the plating is magnetic, and the thin silver coating won't change that.
The reverse isn't as clean. If the magnet doesn't stick, it doesn't automatically confirm sterling. Brass, copper, and nickel silver are all non-magnetic metals that get used as plating bases. So a lack of magnetic pull is encouraging but not conclusive. Think of this test as a quick filter: it can rule a piece out fast, but it can't rule it in on its own.
The test is worth doing first because it takes five seconds. Work through a full set quickly and set aside anything that sticks. You'll have sorted out the obvious non-contenders before getting into slower, more careful tests.
Try the ice test
This one surprises most people. Silver has the highest thermal conductivity of any metal, which means it transfers heat extremely rapidly. If you place an ice cube on a genuine sterling piece, it starts melting almost immediately, noticeably faster than it would on the countertop or on a piece of stainless steel. The silver itself also becomes icy cold to the touch within seconds.
The test works best on flat surfaces, the back of a spoon or a serving piece. Set the ice cube on the metal and watch. Real silver will melt it quickly and evenly. A plated piece over a lower-conductivity base metal will melt ice more slowly. You can run the comparison yourself by setting one cube on the flatware in question and another on a stainless steel surface at the same time. If the flatware melts its cube noticeably faster, that's a good sign.
Like the magnet test, this isn't 100% definitive on its own. But paired with a stamp check, it adds useful confirmation. And it requires nothing but ice, which makes it genuinely practical at an estate sale or while sorting through a box at home.
Look at how it wears
On silver-plated flatware, the thin silver coating wears away at the points of highest contact over time. Check the bowl of spoons, the tips of fork tines, and the edges of knife handles. If you can see a different color metal showing through in those spots, a slightly yellowish or copper-toned base metal, that's plate wearing through. Sterling silver wears too, but it wears as itself. There's no different layer underneath to expose.
The color of the tarnish is another signal. Sterling tends to tarnish to a consistent dark gray or black across the whole piece. Plated items sometimes develop a more uneven, blotchy tarnish, particularly in spots where the silver layer has thinned. This isn't a definitive test either, but it's a useful thing to notice when you're looking at a piece that lacks clear marks.
One more physical tell: on a flatware set, knife blades are almost always stainless steel regardless of whether the set is sterling or plated. That's by design. The handles might be sterling, but the blade won't be. If you're trying to calculate value, keep in mind that the knife handle and all other pieces count toward the silver weight, but the blade itself does not.
What you're actually sitting on if it is sterling
Once you've confirmed your flatware is sterling, the value comes down to weight times purity times spot price, minus what the buyer takes. A silver spot price around $76 per troy ounce makes the current moment a strong time to sell. A standard 5-piece place setting in sterling weighs roughly 6 troy ounces. At today's price, that's about $422 in silver value. After a buyer's commission of around 20%, you'd take home roughly $337 per place setting.
Scale that up and the numbers move fast. A 48-piece set for 12 people contains roughly 80 troy ounces of silver and carries a gross silver value around $4,750 at current prices, or about $3,800 after the buyer's cut. Sets by well-known makers such as Tiffany, Georg Jensen, or Gorham's Chantilly pattern can carry additional collector value on top of melt value, particularly if they're in good condition with all pieces present.
If the hallmarks are unclear, a local jeweler or silver buyer can do a quick appraisal, often for free if you're considering selling to them. Getting one before approaching online buyers is worth the trip. You'll negotiate better when you already know what you have.
