EPNS vs Sterling Silver: How to Tell the Difference
EPNS is silver plate: a thin coat of silver over base metal. Here is how to tell it from sterling in a minute, what each is worth, and when plate is still worth selling.
EPNS stands for Electroplated Nickel Silver.
- It is a copper, nickel and zinc alloy with a thin layer of silver, measured in microns.
- It has no scrap value. Sterling, 92.5% silver, is worth … a gram today.
- The test: a British sterling hallmark has a lion passant. EPNS, EP, EPBM and A1 are plating marks.
- EPNS still sells when the maker, the design or a complete boxed canteen make it worth having.

What EPNS actually means
EPNS stands for Electroplated Nickel Silver. It describes a process developed in the 1840s, shortly after the invention of electroplating, in which a base-metal object is coated with a thin layer of genuine silver using an electrical current. The base is an alloy of copper, nickel and zinc, called nickel silver or German silver even though it contains no silver at all.
The method was perfected and popularised by Elkington & Co. of Birmingham, who held the key early patents. It let manufacturers make pieces with the look of solid silver at a fraction of the cost, and it transformed the Victorian table: middle-class households could suddenly afford settings that looked the part.
EPNS contains real silver, but only as a surface layer measured in microns. That layer cannot be recovered economically, so plate has no scrap value.
EPNS marks and other plating marks, decoded
Plating marks are small stamps in a row, so they are easy to mistake for a hallmark. None of these means solid silver:
| Mark | What it means | Solid silver? |
|---|---|---|
| EPNS | Electroplated nickel silver: silver-plated copper, nickel and zinc alloy | No |
| EP | Electroplated, base metal not stated | No |
| EPBM | Electroplated Britannia metal, a pewter-like tin alloy | No |
| EPWM | Electroplated white metal | No |
| EPGS | Electroplated German silver (nickel silver) | No |
| A1, AA | A plater's quality grade for a heavier silver deposit, not a silver content | No |
| Nickel silver, German silver, Alpacca | Copper, nickel and zinc alloys named for their colour | No silver at all |
| Sheffield plate | Sheet silver fused to copper, roughly 1740 to 1840. A separate collecting field | No |
A maker's name on its own is the other trap. Elkington, Mappin & Webb and Walker & Hall made vast quantities of plate as well as sterling, so the name tells you who made it, not what it is made of.
How to tell EPNS from sterling
The single most reliable method is to look for a British hallmark. Every piece of solid sterling silver sold in the UK above the exemption weight has, by law, been assayed and stamped by an official assay office. A full set of marks has four parts:
- The lion passant: a walking lion, the sterling standard mark for 92.5% silver, used since 1544.
- The assay office mark: a leopard's head for London, an anchor for Birmingham, a rose for Sheffield (a crown before 1975), a castle for Edinburgh.
- The date letter: a single letter giving the year of assay, in a changing typeface and shield.
- The maker's mark: the registered initials or symbol of the silversmith or firm.
EPNS pieces carry none of these. Instead you find the plating letters, often beside a maker's cartouche or trade name, but no lion passant and no assay office symbol. If you cannot find a lion passant, the piece is almost certainly not British sterling. Our guide to reading silver hallmarks and silver purity marks explained go through every symbol.
Physical tests and visual clues
Beyond the marks, a few physical checks help confirm your reading. None is conclusive on its own, but together they build a clear picture.
Plating wears through on fork tines, the backs of spoon bowls and high points. A yellow or coppery colour underneath is a dependable sign of plate.
Sterling is noticeably heavier than plated base metal of the same size, though some base metals are heavy too.
Sterling is not magnetic. If a magnet clings, the piece is certainly not sterling. A clean result does not prove sterling, because most plating metals are not magnetic either.
Old Sheffield plate can show a copper edge or seam where the silver has worn back at a join.
A jeweller's loupe is invaluable. Most people who misread plating marks as hallmarks were looking without magnification. For more home checks see how to tell if silver is real.
EPNS vs sterling at a glance
Sterling silver today:…per gram of sterlingloading the live price…
| EPNS electroplate | Solid sterling silver | |
|---|---|---|
| Silver content | A thin surface layer, measured in microns | 92.5% silver throughout |
| Marks | EPNS, EP, EPBM, A1; no lion, no assay office | Lion passant, office mark, date letter, maker |
| Core | Copper, nickel and zinc alloy | Sterling silver all the way through |
| Wear | Rubs through to yellow or copper | Wears evenly, same metal all the way down |
| Metal value | None worth recovering | Worth its weight at the live silver price |
| A 12-place canteen | Sold as tableware, usually for tens of pounds | About 2.5 kg of sterling holds … of silver today, before any antique value |
The canteen figure is the live value of 2.5 kg of sterling silver, a typical weight for twelve place settings without the steel knife blades. Pattern, maker and condition can add to it. Work out your own with the silver calculator.
Is EPNS worth anything?
As metal, no. No reputable buyer will price EPNS by weight, and if somebody offers to, be careful. But it has value when the object is wanted for what it is:
- Good makers. Elkington, who led commercial electroplating, along with Mappin & Webb, Walker & Hall, James Dixon & Sons and Christofle.
- Complete canteens in their original fitted box, which sell as usable tableware.
- Strong design. Arts and Crafts, Art Nouveau and Art Deco plate is collected on design merit.
- Unusual forms. Epergnes, biscuit boxes, novelty pieces, and hotel or railway ware with a crest.
What is genuinely not worth selling: mixed loose cutlery, plate with the base metal showing through, and unmarked plated hollowware in poor condition. Early Sheffield plate, which predates electroplating, is a separate case: good examples have their own collectors.
Do not overestimate the demand. The market for decorative plate is limited and slow. A handsome Elkington canteen from 1880 is a pleasant thing to own and use; it is not an investment.
When you cannot tell
Some situations make identification genuinely hard, even for specialists:
- Worn or polished marks. Generations of cleaning can erase marks. Do not assume an unreadable piece is sterling.
- No marks at all. Foreign, very early and some provincial silver lacks a British hallmark. Treat an unmarked piece as plate until proven otherwise.
- Partial marks. A single stamp that might be a lion passant or a trade symbol needs magnification and experience.
- Mixed pieces. A sterling tray with a plated handle, or silver with plated repairs.
Foreign silver has its own marks: see our guide to Chinese export silver. If you have silver and plate mixed together, our guide to inherited silver covers how to sort it.

Questions we are asked
What does EPNS mean on silver?
EPNS stands for Electroplated Nickel Silver: a base-metal alloy of copper, nickel and zinc coated with a thin layer of real silver. It is silver plate, not solid silver.
Does EPNS contain any real silver?
Yes, but only as a thin surface layer measured in microns, applied by electroplating. There is no meaningful melt value in that coating, which is why EPNS is worth a fraction of solid sterling.
What is the quickest way to tell EPNS from sterling?
Look for the lion passant. A full British hallmark with a walking lion confirms sterling. Plate carries letters such as EPNS, EP or A1 instead, with no lion and no assay office mark. Use a loupe to read the marks.
Is EPNS worth anything as scrap?
No. The silver layer cannot be recovered economically, so EPNS is never bought by weight. It sells as tableware or decoration, and good makers, boxed canteens and strong designs sell best.
What does A1 mean on silver?
A1 is a plater's quality grade meaning a heavier deposit of silver. It is found on plate, often next to EPNS, and does not mean solid silver.
Is nickel silver real silver?
No. Nickel silver, German silver and Alpacca are alloys of copper, nickel and zinc named for their colour. They contain no silver unless they have been plated.
Is Sheffield plate the same as EPNS?
No. Sheffield plate, made roughly from 1740 to 1840, fuses sheet silver to copper by heat and rolling. It predates electroplating, is a separate collecting field, and good examples can be worth more than ordinary EPNS.
My piece has no marks at all. Is it sterling?
Treat an unmarked piece as plate until proven otherwise. Foreign, very early or provincial silver can lack a British hallmark, so it needs hands-on examination or testing.
