What EPNS means on silver, and what it is worth

Three different things arrive at a valuation day described as silver, and only one of them is. The letters on the base usually settle it in about ten seconds, once you know which letters matter and which are decoration.

What EPNS stands for, and what it is not

EPNS stands for electroplated nickel silver.

Read it backwards, because that is the order in which it is misleading.

Nickel silver is the base. It is an alloy of copper, nickel and zinc, and the name describes its colour rather than its contents: it looks like silver and contains none. It has other names — German silver, alpacca, argentan — and all of them are selling the same illusion.

Electroplated is what was done to it. The finished object was put into a bath and a layer of pure silver was deposited onto it by passing a current through the solution.

So the only silver in an EPNS teapot is the skin, and the skin is measured in microns. A good Victorian plater might lay down twenty; a cheap one, five. Either way it is a coating, not a material.

That is why the question people usually ask — is EPNS real silver? — has an answer that sounds evasive and is not: there is real silver on the surface and none underneath.

Why EPNS silver carries no hallmark

A British hallmark is a guarantee about precious metal content, struck by an independent assay office that tested the metal. Plated goods have essentially no precious metal, so there is nothing to guarantee and they are not hallmarked — ever.

Under the Hallmarking Act 1973 it is also an offence to describe or mark plated wares in a way that suggests they are precious metal.

Which brings us to the thing that fools almost everyone.

Nineteenth-century platers marked their goods with shields, crowns, lions, anchors and single letters in shaped surrounds — arrangements that read, at arm’s length, exactly like a hallmark. They are trade marks. They were designed to look like assay marks and they did their job well enough that people are still misled by them a century and a half later.

The way through is not to squint harder at the shapes. It is to ask a different question:

Is there a standard mark in the row?

A lion passant. A seated Britannia. A millesimal number like .925. Those are the marks that say what the metal is, and only an assay office strikes them. If there is no standard mark, it is not hallmarked silver, whatever else is stamped beside it. What the lion passant means goes through the standard marks properly.

EPNS, EP and EPBM — reading the letters

The letters tell you the process and the base metal. None of them tells you there is silver underneath, because there never is.

Mark	Stands for	The base metal underneath
EPNS	Electroplated nickel silver	Copper, nickel and zinc — no silver
EP	Electroplated	Unstated
EPBM	Electroplated Britannia metal	Tin, with antimony and copper
A1	A plater’s own quality grade	Varies — it is not a standard
STERLING or .925	Solid silver, 92.5%	There is no “underneath”

Two of those rows need a note.

A1 looks official and is not. It was a manufacturer’s claim about the thickness of the plating, made by the manufacturer, checked by nobody. Treat it as advertising.

EPBM is the one that causes real confusion, because Britannia metal and Britannia standard silver share a name and nothing else. Britannia standard is silver of 95.84% purity, higher than sterling, marked with a seated figure of Britannia. Britannia metal is a pewter-like alloy of tin and antimony with no silver in it whatsoever. A piece marked EPBM is plated tin. A piece marked with the Britannia figure is the best silver in the British system. The words are almost identical and the objects are a hundred times apart.

How to tell EPNS from sterling silver

Five steps, in the order that settles it fastest.

1. Find the marks. The base, the underside of a handle, the inside of a foot rim. On flatware, the back of the stem near the bowl.
2. Look for a standard mark, not for “a hallmark.” People search for a group of symbols and find one, because plate has groups of symbols too. Look for the specific thing: lion, Britannia, or a number.
3. Read any plain letters at face value. EPNS, EP, EPBM, A1, “silver on copper”, “nickel silver” — all plate, all saying so.
4. Check the wear. This is the physical test and it is the one that cannot be faked. Plate wears through at rims, high points and the front edges of spoon bowls, and what shows through is a different colour. Solid silver wears too, but it wears silver-coloured, because there is nothing else in it.
5. Weigh it in your hand. Sterling is noticeably dense. This is the weakest test of the five and the one most often relied on, so treat it as a hint rather than an answer — a heavy EPNS tray with a loaded base will beat a thin sterling one every time.

A magnet is worth mentioning only to dismiss it. Silver is not magnetic, but neither is brass, copper, aluminium or nickel silver. A magnet rules out iron and steel and tells you nothing at all about the difference this page is describing.

EPNS or Old Sheffield plate? Look at the colour underneath

Before electroplating there was Sheffield plate, and telling the two apart is worth a minute of your time, because one of them is collected in its own right.

From roughly the 1740s to the 1840s, a sheet of silver was fused to a copper ingot and the two were rolled out together, so the finished sheet is a sandwich. It was worked like silver and some of it is very good indeed.

From about 1840, electroplating did the same job far more cheaply and could coat shapes that could not be rolled. It took the market within a generation.

The tell is the colour of the metal showing through at a worn edge:

• A warm copper blush — Old Sheffield plate. Collected, and ruined by heavy replating.
• Grey or yellowish-white — electroplate over nickel silver. That is EPNS.

Old Sheffield plate also tends to have seams where the sheet was wrapped, and edges disguised with an applied silver wire, because a cut edge would show the copper filling. Electroplate has no seams of that kind: the object was made first and dipped afterwards.

Is EPNS silver worth anything?

Less than people hope, and more than nothing.

Not as metal. The plating on a large tray might amount to a gram or two spread over the whole surface, and recovering it costs more than it is worth. This is why a scrap dealer will weigh your sterling and hand the plate back. EPNS is not scrap silver, and no refiner prices it as though it were.

As an object, sometimes quite a lot. The value is in what it is, not what it is made of:

• A recognised maker — Elkington, Mappin & Webb, Walker & Hall
• An unusual or characterful form rather than a plain tray
• A complete service, unbroken
• Real design quality, particularly Arts and Crafts or Art Deco
• Condition: plating intact, no copper or grey showing at the rims

Against that, a worn Victorian tray with base metal showing at every edge is worth very little, and the cost of replating it will exceed what it would then fetch.

The honest way to find out which of those you have is not to ask what EPNS is worth in general — that question has no answer — but to look at what pieces like yours have actually sold for. What an auction result actually says is about reading those figures properly, because a realised price, an estimate and a hammer price are three different numbers and only one of them is evidence.

What to do with EPNS you have inherited

Do not have it replated as a matter of course. On Old Sheffield plate it destroys the value outright. On EPNS it costs more than the piece is usually worth afterwards.

Do not over-polish it. Every polish removes a little of a coating that is only microns thick. The bald patches on old plate are polishing, not use.

Do use it. This is the part people miss. A plated tea service is a tea service, it will not tarnish faster than sterling, and its resale value is low enough that using it costs you almost nothing. A great deal of EPNS sits in lofts protecting a value that was never there.

Do check the marks before you sell as a lot. Plated and solid pieces travel together in the same box from the same house, and it is common for one genuinely hallmarked item to be sold as part of a tray of plate because nobody turned it over.

What the letters actually settle

EPNS answers the question what is this made of completely and finally: a base metal with a skin of silver, no hallmark, no scrap value. What it does not answer is whether the object in your hand is worth keeping, and those are different questions with different evidence behind them.

The marks tell you the material. Only the sold lots tell you the price.
