Sterling Silver vs. Silverplate: Hallmarks and How to Tell the Difference

Sterling silver and silverplate can sit an inch apart in a display case and look, to an untrained eye, like the same thing. Both take a high polish and carry the same cool, heavy shine on a tea service or a carving set. But one is silver through and through, worth its weight and then some, while the other is a thin skin of silver over a base metal that was never silver at all — a difference that can mean thousands of dollars on an otherwise identical pattern.

Neither metal keeps its secret for long, though. Sterling and silverplate are marked, and once you know what those marks actually say — and what they don't — you can sort almost any piece of flatware or hollowware in under a minute. This guide covers the marks, the makers who used both metals under one name, and the honest, non-magic ways to tell one from the other.

What Sterling Silver Actually Is

The 92.5% Standard

Sterling silver is not pure silver — pure silver is too soft to hold its shape as a spoon or a candlestick. Sterling is an alloy of 92.5% silver and 7.5% other metal, almost always copper, which gives the metal enough strength to be worked and to survive daily use. That 92.5% figure is a legal standard in most countries, not a marketing term, and it is the number every genuine sterling mark is certifying.

American Sterling Marks

American sterling is usually the most straightforward metal to identify: look for the word "STERLING" stamped somewhere on the piece, sometimes alongside "925" (shorthand for 92.5%). Major makers — Gorham, Towle, International Silver, Reed & Barton — stamped their sterling this way from the mid-19th century on, often with a pattern name beside the maker's mark.

Coin Silver — America's Earlier Standard

Before sterling became the American norm, most 18th- and early 19th-century American silver was made to a lower, less consistent standard commonly called coin silver, roughly 90% pure (from the practice of melting down silver coinage to make it). Coin silver pieces are usually marked only with the maker's name or initials, since the word "sterling" hadn't yet become the formal American standard. An unmarked, ambiguous early American piece is often coin silver rather than a mystery metal.

Reading English Hallmarks

The Lion Passant

English sterling carries a fuller, more formal system than American silver: a true hallmark, applied by an official assay office after the metal was tested. The mark that certifies the sterling standard itself is the lion passant — a lion shown walking, in profile, with one forepaw raised. If a piece is genuinely English sterling, the lion passant (in one of its period forms) should be there. Its absence is one of the fastest ways to rule sterling out.

Town Mark, Date Letter, Maker's Mark

Around the lion passant, a full English hallmark adds three more marks: a town mark for the assay office that tested the piece (a leopard's head for London, an anchor for Birmingham, a castle for Edinburgh); a date letter, a single letter in a distinctive typeface that cycles through the alphabet in roughly 20-year runs and, checked against a published hallmark chart, pins the piece to a specific year; and a maker's mark, usually the silversmith's initials in a shaped punch. Together, these four marks — standard, town, date, maker — turn a piece of English silver into a small, dated, attributable document.

Lion's Head Erased — A Different Mark Entirely

One mark worth knowing so you don't confuse it with the lion passant: the lion's head erased — a lion's head only, shown as if torn off at the neck rather than a full walking lion. This mark belongs to a different, short-lived period of English silver (the higher-purity Britannia standard of the years around 1697–1719) and is not interchangeable with the lion passant of ordinary sterling. If you see a lion's head rather than a full walking lion, you are looking at a different standard mark, not a stylistic variant of the same one.

What Silverplate Is — And What the Marks Mean

EPNS and the Electroplating Process

Silverplate is a completely different construction: a base metal core with a thin layer of silver applied to the surface. The process was industrialized in the 1840s, and the most common mark is EPNS, for Electroplated Nickel Silver. It's worth being plain about that name: despite it, "nickel silver" (also called German silver) contains no silver at all — it's an alloy of copper, nickel, and zinc, prized only because its pale, cool color resembles silver. EPNS deposits a thin layer of genuine silver, by electric current, onto that silver-free base. The plating is real silver; the metal beneath it never was. Other marks you'll meet include plain "EP" (electroplate) and "EPBM" (electroplated Britannia metal, a tin-based base).

Quadruple Plate, Triple Plate, A1

American silverplate makers developed their own vocabulary for plating thickness — mostly marketing shorthand rather than a precise technical standard. "Quadruple plate," "triple plate," and grading marks like "A1" were used to suggest a heavier coating than a competitor's. These terms give useful context for a piece's era and quality tier, but they don't substitute for a genuine sterling mark, and their absence doesn't automatically mean thin or poor plating.

The Maker Trap: Same Name, Both Metals

Here is the detail that catches the most collectors: major manufacturers like Gorham and the various Rogers companies (Wm. Rogers, F.B. Rogers, Oneida's Rogers lines) made both sterling and silverplate over their long histories, sometimes in nearly identical patterns. The company name on the back tells you almost nothing about the metal — you have to read the specific mark every time. A Rogers piece stamped "STERLING" and one stamped "EPNS" or "1847 Rogers Bros." (a well-known Rogers plate trademark) are two different metals wearing the same family name.

Five Ways to Tell Them Apart

Read the Marks First

Always start here. "STERLING" or "925" means sterling; "EPNS," "EP," "EPBM," "quadruple plate," or a maker's plate-line trademark means silverplate. This single step resolves the vast majority of pieces before you need any other test.

Look for Wear-Through

Silverplate wears unevenly, because it's a coating rather than a solid metal. On flatware, check the back of spoon bowls and the tips of fork tines — the spots that rub against a plate or a mouth thousands of times. If you see a dull yellow or grayish base metal showing through the silver, especially in a coppery or brassy tone, that is a plated piece with its coating worn away, and no genuine sterling piece will ever show this, since it is the same metal all the way through.

Weight and Heft

Sterling tends to feel heavier and denser than plate of similar size — a useful secondary clue once you've handled enough of both, though it's a feel to develop over time, not a measurement to rely on alone.

The Magnet Test — Used Carefully

A small magnet is a popular pocket test: sterling silver is non-magnetic, so if a magnet clings firmly to a piece, you can be confident it isn't solid sterling. But treat this as an elimination test only, never as proof. Many silverplate base metals — copper, brass, nickel silver — are also non-magnetic, so a piece that doesn't attract a magnet could still easily be plate. The magnet can rule pieces out; it cannot rule sterling in.

Patina Over Time

Left unpolished, sterling tarnishes evenly across its whole surface, since the entire object is the same alloy. Silverplate more often tarnishes and wears unevenly, because plating thickness is rarely perfectly consistent across a piece. As with weight, read this alongside the marks, not instead of them.

Caring for Sterling and Silverplate

Polish Sparingly

Both metals benefit from restraint. Every polish removes a microscopic layer of metal, which sterling can absorb for generations but silverplate cannot — over-polishing a plated piece is one of the most common ways collectors accidentally wear through to the base metal beneath. Polish only when tarnish is visible, use a proper silver polish rather than an abrasive cleaner, and work gently around engraving and raised ornament, where plating is thinnest.

Storage

Store silver away from rubber, wool, and direct sunlight, all of which accelerate tarnish, ideally wrapped in anti-tarnish cloth. This one habit preserves either metal's finish over the long run better than any amount of after-the-fact polishing.

At a Glance

• Sterling silver is 92.5% silver throughout, marked "STERLING" or "925" in American work.
• English sterling carries a full hallmark: the lion passant standard mark, a town mark, a date letter, and a maker's mark.
• "Nickel silver" and "German silver" contain no silver at all; EPNS plates a thin layer of genuine silver over that silver-free base.
• Major makers like Gorham and the Rogers companies produced both metals — read the specific mark, never assume from the name alone.
• Wear-through to a yellow or coppery base metal, especially at high-touch points, confirms plate; the magnet test only rules sterling out, never in.
• Treat age and value estimates as informed guidance rather than certainty, and weigh the marks, wear, and weight together rather than any single test alone.

Frequently Asked Questions

Does EPNS silver contain any real silver?

Yes, but only as a thin plated surface layer. EPNS is Electroplated Nickel Silver — genuine silver applied by electric current over "nickel silver," an alloy of copper, nickel, and zinc that despite its name contains no silver at all. The shine is real silver; the metal beneath it is not.

Is the lion passant mark the same as a lion's head?

No. The lion passant — a full lion shown walking, in profile — is the standard mark for English sterling. A lion's head erased (head only, as if torn off at the neck) belongs to a separate, higher-purity Britannia standard from a specific historical period. A lion's head means a different mark, not a stylistic variant of sterling.

Can a magnet prove a piece is sterling silver?

No. A magnet can rule sterling out — if it clings firmly, the piece isn't solid sterling — but it can't rule sterling in. Many silverplate base metals are also non-magnetic, so a piece the magnet ignores could still be plate. Treat it as one clue among several, never final proof.

Why does a maker's name alone not tell me the metal?

Because major manufacturers, including Gorham and the various Rogers companies, produced both sterling and silverplate lines, sometimes in very similar patterns. The name confirms who made it, not what it's made of — read the specific mark stamped on that piece every time.

Conclusion

Sterling and silverplate reward the same simple habit: read the marks before you trust the shine. A lion passant, a "STERLING" stamp, or a full English hallmark tells you the silver runs all the way through; "EPNS" or a plating-grade mark tells you it doesn't, no matter how heavy or brightly polished the piece feels in your hand. Once you know what to look for — and just as importantly, what a magnet or a maker's name can't tell you on their own — a case of unlabeled family silver stops being a mystery and starts being a set of pieces you can read at a glance. The same close attention to material and construction runs through how to identify brass, bronze, and copper, and into what actually makes an antique worth more.
