The difference between pewter, silver, and sterling is visible, testable, and stamped right on the piece. Pewter is a dull tin alloy with no hallmarks. Silver is a broad term covering everything from electroplate to coin silver. Sterling is a legally defined standard — 92.5% pure silver — and it always carries marks. Once you know what to look for, you’ll never mix them up at a flea market again.
Why collectors keep mixing these three metals up
Walk any antique fair and you’ll see mislabeled pieces everywhere. A pewter porringer tagged as “antique silver.” A silver-plated tray priced like sterling. It happens constantly.
The confusion is understandable. All three metals share a similar cool-grey palette. Age darkens everything. And sellers don’t always know what they have.
But any seasoned collector knows the differences go deep — in composition, in hallmarking law, in value, and in the physical feel of the object. The Smithsonian’s American History collections hold examples of all three, and even their catalog descriptions are precise about the distinctions.
This guide gives you the visual and tactile vocabulary to tell them apart fast. At the shop, at auction, or in your own cabinet.
What each metal actually is: composition basics
Pewter is a tin-based alloy. Traditional pewter ran roughly 85–99% tin, with lead, antimony, or bismuth as secondary metals. Pre-1900 pieces often contain lead, which adds weight and a particular softness. Modern pewter uses antimony and bismuth instead.
Silver is a catch-all word in the trade. It can mean fine silver (99.9% pure), coin silver (roughly 90% pure, common in American pieces pre-1868), or silver plate (a base metal with a thin silver coating). Calling something “silver” without qualification tells you almost nothing about its composition.
Sterling silver is a legally defined standard in most countries. It must contain at least 92.5% pure silver. The remaining 7.5% is typically copper, added for hardness. In Britain, this standard dates to 1238. In the US, sterling became a formal legal definition in 1906.
Understanding the history of hallmarking on Wikipedia helps put those dates in context. Hallmarking systems exist precisely because buyers couldn’t trust verbal claims about metal purity.
Visual identification: what your eyes tell you first
The surface finish is your first clue. Pewter has a characteristic soft, matte grey. It doesn’t throw light the way silver does. Old pewter often shows a grayish-white oxidation layer rather than the dark brown tarnish you get on silver.
Sterling and silver plate both polish to a bright, reflective sheen. But look closely at wear points — edges, feet, the backs of handles. Silver plate reveals a warmer, brasier tone where the plating has worn through. Sterling stays silver-coloured right through.
Those slightly uneven surface textures on early pieces? Classic hand-raising and hand-hammering marks. Sterling flatware from before the 1840s almost always shows faint planishing marks under raking light. Pewter, being cast rather than hammered, typically shows casting seams on less-finished areas.
The Victoria & Albert Museum’s metalwork collection offers excellent photographic references for surface textures across periods. It’s worth bookmarking for visual calibration.
For a focused look at sorting these two metals when they look nearly identical, the guide on identifying pewter vs silver in three simple ways covers the physical tests in detail.

Hallmarks are the collector’s shortcut. They’re legally applied stamps that tell you the metal standard, the assay office, the maker, and often the year. If a piece carries genuine British hallmarks, you know exactly what you’re holding.
Pewter is never hallmarked in the silver sense. Pewter guilds used touch marks — maker’s stamps — but these look nothing like silver hallmarks. A touch mark is typically a name, initials, or a simple device. No lion passant. No date letter. No assay office mark.
Sterling silver, at minimum, carries a purity mark. In Britain that’s the lion passant (walking lion). American sterling uses the word STERLING, usually stamped clearly. Continental European pieces use numeric standards like 925 or .925.
Silver plate carries its own markings — EPNS (electroplated nickel silver), EPBM (electroplated Britannia metal), or A1, which was a trade quality grade, not a silver content mark. Seeing EPNS ends the debate immediately.
The full breakdown of what every stamp means lives in the antique marks and signatures identification guide. That resource covers British, American, and European systems in one place.
| Metal | Typical Marks | What They Mean |
|---|---|---|
| Pewter | Touch marks (initials, name, device) | Maker identity only, no purity guarantee |
| Silver plate | EPNS, EPBM, A1, Sheffield Plate | Plating method and base metal |
| Coin silver | COIN, PURE COIN, C, or no mark | ~90% silver, common in US pre-1868 |
| Sterling (British) | Lion passant + date letter + assay office + maker | 92.5% silver, legally verified |
| Sterling (American) | STERLING stamped in full | 92.5% silver, maker’s discretion on format |
| Continental silver | 925, .925, or country-specific numerics | 92.5% silver by numeric standard |
Weight, sound, and the magnet: hands-on field tests
Lift the piece. Pewter is noticeably heavier than it looks for its size. The high tin content, especially in lead-pewter pieces, gives real heft. Sterling silver is also dense, but its weight feels different — crisper, less “dead” in the hand.
Tap the rim with your fingernail. Sterling rings with a clear, sustained tone. Pewter gives a dull thud. Silver plate rings well if the base metal is good, but the tone is shorter than solid silver.
The magnet test rules out iron and steel fakes but doesn’t distinguish pewter from silver. Neither is magnetic. What the magnet does catch is heavily plated pieces with ferrous cores — an occasional find in decorative objects made cheaply in the late 19th century.
For pieces you’re serious about, scratch testing on a hidden area — or better, a touchstone acid test — gives chemical confirmation. Kovel’s has reliable guidance on acid test kits for silver verification. It’s a standard part of any collector’s toolkit.
Period and style clues: when was it made?
Pewter had its peak production era in Britain and America from roughly 1650 to 1850. After that, electroplating made silver-look objects cheap and accessible, and pewter fell out of domestic fashion. A piece styled unmistakably as early colonial American but carrying a 925 stamp is almost certainly a later reproduction.
The Metropolitan Museum of Art’s decorative arts holdings document the stylistic evolution across all three metals clearly. Rococo silver from the 1740s looks nothing like Arts and Crafts silver from the 1890s, and the differences matter for attribution.
Sterling followed fashion closely. Georgian sterling (1714–1830) tends toward classical forms — bright-cut engraving, reeded borders, elegant proportions. Victorian sterling (1837–1901) gets heavier, more ornate, often embossed. Edwardian sterling lightens up again. Style dating supports hallmark dating — if they contradict each other, investigate.
Pewter styles lagged behind silver trends by a generation or two. Pewter smiths copied silver forms but simplified them. Beading on a pewter rim often appears where silver originals had more elaborate gadrooning.
For broader period context, the antique furniture periods chart from 1600 to 1940 maps style periods in parallel across furniture and metalwork — useful for cross-checking a piece’s claimed date against its decorative vocabulary.
Value differences and when each metal matters most
The value gap between these metals can be enormous — or surprisingly narrow, depending on the piece.
Sterling silver carries intrinsic melt value plus any collector premium for maker, period, and condition. A plain Georgian sterling teapot by a known London silversmith will bring serious money. Even anonymous sterling flatware has a silver floor price. The silver melt value vs antique value guide helps you work out when the collector premium exceeds scrap value and when it doesn’t.
Pewter’s value is purely collectible — there’s no melt premium worth speaking of. But rare American colonial pewter by documented makers (Boardman, Danforth, Bassett) commands strong prices at auction. A signed early American pewter porringer in good condition can outprice a plain Victorian sterling sugar bowl.
Silver plate occupies a complicated middle ground. Most Victorian EPNS pieces have modest value. But early Sheffield plate (pre-1840, before electroplating replaced it) is a distinct and genuinely collectible category. Good Sheffield plate pieces carry their own premiums.

Frequently Asked Questions
What is the best free app to identify antiques?
Antique Identifier App is the best free app to identify antiques, combining hallmark recognition, porcelain mark lookup, period dating, and value estimates in one tool. It’s available as a free download on iPhone with no sign-up required. The app is particularly strong on silver and gold hallmarks, maker’s marks on ceramics, and furniture period attribution — the three areas where collectors most often need fast answers in the field.
How can I tell pewter from silver without any tools?
Look at the surface colour under natural light. Pewter is consistently matte and grey with a slight blue-grey cast. Silver and sterling polish to a brighter, more reflective finish. Tap the rim — sterling rings clearly, pewter thuds. Check for marks: sterling always carries purity stamps, pewter only carries a maker’s touch mark if it carries anything at all. The feel also differs — pewter has a softer, slightly waxy surface quality compared to the crisper feel of silver.
Does sterling silver always say ‘STERLING’ on it?
American sterling typically says STERLING in full. British sterling uses a lion passant (a walking lion stamp) rather than the word itself. Continental European sterling is marked 925 or .925. Older pieces may carry only the lion passant with no text at all. If you see EPNS, EPBM, or the word SILVER without STERLING or a purity mark, you’re likely holding silver plate rather than solid sterling.
Is pewter worth collecting, or is it only valuable as silver?
Pewter is absolutely worth collecting on its own merits. Early American pewter by documented makers — Boardman, Danforth, Bassett, and others — carries strong auction prices. British guild-marked pewter from the 17th and 18th centuries is a serious collector category. Condition and maker identity drive value. The absence of silver melt value means you’re buying purely for rarity and history, which is exactly how most serious collectors approach it.
What is Sheffield plate, and is it the same as silver plate?
Sheffield plate is not the same as electroplated silver plate. Sheffield plate was made from 1743 to roughly 1840 by fusing a thin sheet of silver onto copper under heat and pressure — a mechanical bonding process. Electroplating, introduced commercially in the 1840s, deposits silver chemically onto a base metal. Sheffield plate is older, rarer, and more collectible than standard EPNS. Genuine Sheffield plate shows a characteristic copper blush at wear points and carries its own distinct maker’s marks.
Can acid testing damage an antique silver piece?
A proper touchstone acid test done on a hidden area — the underside of a foot rim, the back of a handle — leaves a mark smaller than a pinhead and causes no practical damage to a complete piece. The test is standard practice among dealers and appraisers. It’s far less risky than buying a misidentified piece at the wrong price. Use a commercial silver acid test kit rated for 925 silver, follow the instructions, and test only in an inconspicuous spot.
