Silver plate vs sterling: how to tell at the shelf
Silver plate vs sterling comes down to the stamp. "Sterling", "Ster." or "925" claims solid sterling; EPNS, EP, "Silver Plate" or "Triple Plate" means plate; and no stamp means no claim either way. A stamp is a claim, not a test, so the wear and the build still matter.
Turn the piece over. Underneath, on the back of the handle or along an inner edge, is where the maker said what it is made of, or chose to say nothing.
At the shelf: flip it, read the stamp, check the edges for wear, then price from sold listings for the same maker and pattern. If nothing says sterling, price it as plate.
What marks mean sterling silver?
Sterling means at least 925 parts of silver in every 1,000, which is 92.5%. The other 75 parts, 7.5%, are usually copper. The FTC's jewelry guides set the legal line at the same number: under 16 CFR 23.5(b)(2), "Sterling" and "Ster." may be misleading on anything below 925/1,000ths pure silver.
| Stamp | Reads as |
|---|---|
| Sterling, Ster. | Sterling |
| 925, .925 | Sterling, written as parts per thousand |
| Coin, Coin silver | At least 900/1,000 pure silver, a lower bar than sterling |
| 800, 900 | Continental silver of slightly lower purity than sterling |
On a spoon or fork, read the back of the handle first, then the back of the bowl or the tines. Stamps on other pieces are often on the underside or inner edge. That order is a rule of thumb, not a standard.
Silver plate vs sterling: which marks mean plate?
Plate is a thin coat of silver over base metal. The marks that say so are EPNS, EPBM and "Silver Plate", with EP beside them. On the US shelf the commonest are Triple Plate and Quadruple Plate.
| Mark | What it means |
|---|---|
| EPNS | Electro Plated Nickel Silver; widely used in the UK, less often in the US |
| EPBM | Electroplated Britannia metal, a tin-based alloy |
| EP, Silver Plate | Plate |
| Triple Plate, Quadruple Plate | Plate; the number counts the coatings on the base metal |
How do you tell sterling from silver plate by its marks?
Most marks answer themselves. Four do not, and each one changes what you do. These are rules of thumb, not a grading standard.
| What you see | What to do |
|---|---|
| Lone "Sterling", no maker | Check wear and build, then comp before you pay. |
| Letters in shields, no standard mark | Do not list as silver on the shield's say-so. |
| Marked or labelled "Weighted" | Comp as weighted. Do not price by weight. |
| No mark at all | Pay as if plate. Test it, or list it "unmarked, not tested". |
Knives are the trap. Antique Cupboard, a dealer in sterling flatware, describes its hollow-handle pieces as a sterling handle with a stainless or silverplated blade, and says hollow handle items "were usually not stamped." So on a knife, a stamp on the blade speaks for the blade only. Read a sterling claim from the handle; a blank handle is unmarked.
What if the stamp is only a maker's name, or there is none?
A maker's name, a brand or a pattern name with no sterling word makes no sterling claim. It does not say plate either, because plated pieces may say EP, EPNS or Silver Plate, or nothing at all. A worn-out stamp you cannot read has made no claim, either.
Rule of thumb: no sterling word means not sterling. At the shelf, pay as if it is plate unless a mark or a test says otherwise, and write "sterling" in a listing only with one of them behind it.
Wear is the free evidence: yellow, reddish or dark metal showing through on handles and edges means the plating is wearing off. If the piece is worth the fee, an assay office can test most items by X-ray fluorescence (XRF) without taking a sample, because the metal cannot be known by touch, taste or sight. Otherwise list what you can see: the maker, the pattern, "silver plate" if the mark says so, or "unmarked, not tested."
Does a stamp that just says "silver" mean sterling?
No. The FTC's guides say the unqualified word "silver" may be misleading unless a fineness number comes right before it, such as "750 silver" (16 CFR 23.5(b)(1)). Plate names use the word too: Nevada Silver, Sonora Silver and Silverite are all names used for plate. Read "Sterling" or a fineness number such as 925, not "silver".
Inference, not law: a US-made piece stamped only "Sterling", with no maker's name or trademark, deserves a second look. The reason is in the aside below.
Will a magnet stick to sterling silver?
No, but a magnet that does not stick proves little. Blake Brothers, a wholesale jewelry supplier, says a magnet that sticks means the piece is almost certainly plated. One that slides off settles nothing, because some base metals are not magnetic either. Acid kits are no better: a kit built on acids and reagents reads only the surface layer, so a plated item can come back as silver.
Is heavy hollowware always solid sterling?
No. Weighted sterling is a thin silver shell over a filler, so heavy does not mean solid. Weighted describes the construction, not the silver: a core of cement, pitch or wax poured inside bowls, dishes, candlesticks, boxes and condiment shakers. Vintage pieces may not be labelled "Weighted", and a candlestick weighing a few kilograms might not be all silver.
That breaks the scrap math. Metal value is weight in troy ounces, times 0.925, times today's price per troy ounce. Let P be today's price of one troy ounce of silver: a solid sterling piece that weighs 2 troy ounces holds 2 x 0.925 x P = 1.85 x P dollars of silver. Plug in P from a market page you trust; no figure is printed here.
Rule of thumb: run the sum only on stamped flatware you are buying by weight, where nothing is filled or swapped. A knife with a blade that is not sterling, a weighted piece or plate puts something on the scale that is not sterling, so the sum overstates the silver. For those, sold listings are the better guide.
How do you read British hallmarks on silver?
This is for pieces that came from Britain. For sterling, look for the lion passant, a walking lion with one paw raised, which indicates 925 parts per thousand. Today's four UK assay offices each stamp their own town mark: a leopard for London, an anchor for Birmingham, a rose for Sheffield and a castle for Edinburgh.
How do you check what it sold for before you buy?
Search eBay sold listings, not asking prices, for the same maker, pattern and piece type, and add "sterling" only if the piece carries the mark. As metal, plate is worth very little, so sold listings are the only guide to what it fetches. The full method is in checking sold comps before you buy at thrift. Flatware and hollowware can turn up at estate sales, so estate sale sourcing for eBay resellers is the next read, and what to buy at thrift stores and what to skip is the category map.
Today: pick one piece of flatware you own or spot at your next stop, turn it over and run it through the tables above. Then search its maker and pattern in eBay sold listings.

Disclosure Thrift Routes is published by the team behind FlowLister. FlowLister is AI eBay listing software that turns item photos into complete eBay listings. It writes the title, description, category, item specifics, price and shipping for an eBay listing in about 30 seconds, and it prices each item from recent eBay sold comps and shows the sold listings behind the number. It is AI, so it misses things. We built it, so treat this as a disclosure, not a review. The guides and calculator work the same if you never open it.
