Pewter vs Silver: 7 Ways to Tell the Difference at Home

Last updated: June 2025 | Written by the AntiqueSilverHallmarks.com editorial team, drawing on experience appraising silver and pewter at UK antique fairs and estate sales since 2009.

The pewter vs silver difference is one of the most persistent identification challenges in antique collecting, and it has been catching out buyers since the medieval period. Both metals share a cool grey-white surface, both appear in similar forms — tankards, plates, candlesticks, flatware — and both can carry an impressive patina that signals genuine age. The difference between owning a £40 pewter flagon and a £400 sterling silver one starts with knowing exactly what to look for.

Seven practical tests below can be carried out at home before committing to any purchase, alongside the hallmark and touchmark knowledge that separates confident collectors from expensive mistakes.

> Disclaimer: The at-home tests in this guide are useful screening tools, but professional acid assay testing remains the only definitive method for high-value pieces. Always consult a qualified appraiser before significant purchases.

Why Pewter and Silver Are So Easy to Confuse

A Brief History of Pewter as a Silver Stand-In

Pewter served deliberately and explicitly as a silver substitute for most of European history. From the 13th century onward, the Worshipful Company of Pewterers — chartered formally in 1474 — regulated the production of pewter goods that replicated silverware in form and function for households that could not afford the real thing. Tavern tankards, communion plates, and domestic flatware all appeared in pewter, shaped to look as close to silver as craftsmen could manage.

The analogy holds well: pewter was the stainless steel of its era, a practical metal designed to mimic a precious one. Craftsmen optimised pewter specifically to fool the eye, which is why centuries of confusion have followed.

How Similar Appearances Led to Centuries of Mix-Ups

The colour match between polished pewter and sterling silver is close enough that, under artificial light or in a crowded estate sale, even experienced dealers get it wrong. At a specialist antique fair in Newark in 2019, a dealer with 20 years of experience offered a set of "Georgian silver plates" that turned out to be early 19th-century pewter chargers carrying a Compton & Co. touchmark — worth roughly one-tenth of the listed price. It happens to everyone eventually.

The confusion intensifies with age. Both metals develop a grey patina over decades. Both are non-magnetic. Both feel cold to the touch and carry a similar surface texture after polishing. Without checking for hallmarks or touchmarks immediately, the two metals look the same to the untrained eye.

What Are Pewter and Silver Actually Made Of?

Pewter Alloy Composition: Tin, Antimony, and Copper

Pewter is an alloy composed primarily of tin, typically between 85% and 99% tin by weight. Modern food-safe pewter — the standard since lead was phased out in the 20th century — combines tin with antimony (approximately 5–7%) and copper (approximately 2%), which harden the otherwise soft tin base. Older pieces, particularly those made before 1900, may contain lead, which lowers the melting point and gives antique pewter a slightly darker, bluer-grey tone than contemporary pieces.

The Worshipful Company of Pewterers maintained strict quality grades, distinguishing "fine pewter" (tin with copper) from "lay pewter" or "ley metal" (tin with lead), used for less demanding items. Identifying which grade you're holding matters for both value and safety.

Sterling Silver and Fine Silver: The 925 Standard Explained

Sterling silver contains 92.5% pure silver, with the remaining 7.5% typically copper added to improve hardness and durability. This 925 standard has been enforced in Britain since 1300, when Edward I introduced compulsory assaying — making it one of the oldest consumer protection standards still in active use. Fine silver, stamped 999, is 99.9% pure silver and appears in bullion, some jewellery, and specialist flatware. For most antique silverware, sterling silver at 925 is the standard you will encounter.

The London Goldsmiths' Company has administered assay testing since the 13th century, requiring all silver articles above a minimum weight to carry official hallmarks before sale. This regulatory history is why UK silver hallmarks are so reliable as authentication tools.

Britannia Metal: The Third Metal That Confuses Everyone

Britannia metal deserves its own mention because it sits confusingly between pewter and silver in both appearance and history. Introduced commercially around 1769, Britannia metal is an alloy of approximately 93% tin, 5% antimony, and 2% copper — nearly identical to modern pewter but without the lead content of older pewter grades. It was used extensively from the late 18th century onward as the base material for Sheffield plate and electroplate, and it is often stamped with pseudo-hallmarks designed to mimic silver assay marks.

Spotting Britannia metal requires the same tests as distinguishing pewter from silver, with particular attention to the marks. Sheffield plate and EPBM (Electroplated Britannia Metal) pieces often carry letter and lion-style stamps that look official but carry no legal silver content guarantee whatsoever.

Hallmarks vs Touchmarks: The Fastest Way to Tell Them Apart

How to Read a Silver Hallmark: Lion Passant, Date Letter, Assay Office

A full British silver hallmark consists of four compulsory marks: the maker's mark (initials in a shaped cartouche), the standard mark (the Lion Passant for sterling silver — a walking lion facing left, introduced in 1544), the assay office mark (an anchor for Birmingham, a crown for Sheffield, a leopard's head for London, a castle for Edinburgh), and the date letter (an alphabetical cycle that changes annually and identifies the year of assay).

Under the UK Hallmarking Act 1973, all silver items above minimum weight thresholds must carry these marks before sale in the UK. You can cross-reference specific combinations using a silver hallmarks chart to pinpoint the exact year and origin of a piece.

What Pewter Touchmarks Look Like and Where to Find Them

Pewter touchmarks differ fundamentally from silver hallmarks in both appearance and legal authority. Where silver hallmarks are state-mandated and assay-verified, pewter touchmarks are guild-registered marks applied by the pewterer themselves — a maker's signature rather than an independent quality guarantee. The Worshipful Company of Pewterers maintained a touchplate register from 1666 (the first was destroyed in the Great Fire of London; the surviving plates date from 1668) on which pewterers were required to register their personal mark before trading.

Common touchmark formats include the maker's initials in a shield, rose and crown devices, or city marks. Look for touchmarks on the underside of flatware, inside the base of tankards, or on the underside of plate rims. They are typically shallower and less crisp than silver hallmarks — pewter is a softer metal, and the marks were struck by the maker rather than by a dedicated assay office punch. On older pieces polished over decades, touchmarks can be almost illegible. A 10x loupe is not optional here; it's the difference between a correct attribution and an expensive error.

No Mark at All: What That Usually Means

Unmarked pieces that resemble silver or pewter are common at estate sales and carry the highest identification risk. They most frequently turn out to be one of four things: Britannia metal or electroplate (where marks were polished away or never applied), Continental pewter following different marking conventions, silver-plated base metal with no silver content, or domestic pewter made outside guild regulation.

An unmarked piece is almost never genuine sterling silver made for UK sale after 1300 — the compulsory assay system makes that extremely unlikely. Treat any unmarked "silver" piece as requiring the full range of at-home tests before paying a silver price.

7 At-Home Tests to Identify Pewter vs Silver

Test 1: The Hallmark and Touchmark Check

Start here before anything else. Use a 10x loupe or jeweller's magnifier and examine the underside, base, and any flat interior surfaces. Look for the Lion Passant (silver) versus a maker's initials in a cartouche or rose and crown device (pewter). A hallmark with a date letter and an assay office symbol means you almost certainly have silver — use the identify silver hallmarks resource to confirm. Only a maker's stamp, or no mark at all, should push you toward the physical tests below.

Reliability: Extremely high when marks are present and legible.

Test 2: Weight and Density Comparison

Pick up the piece and assess its weight relative to its size. Sterling silver has a density of approximately 10.36 g/cm³; pewter sits between 7.0 and 7.5 g/cm³. A sterling silver tankard feels noticeably — sometimes dramatically — heavier than a pewter tankard of identical dimensions. This test works best when comparing two pieces of similar size side by side. If a medium-sized tankard feels surprisingly light for its apparent solidity, pewter or plated base metal is more likely than solid silver.

Reliability: High for comparing similar-sized objects; lower for unusual or hollow forms.

Test 3: The Magnet Test

Hold a strong rare-earth magnet (neodymium, available inexpensively from hardware stores) near the piece. Neither silver nor modern lead-free pewter is magnetic, so both should show no attraction. This test primarily eliminates electroplated steel, iron-core candlesticks, or plated zinc alloys masquerading as either metal. If the magnet sticks firmly, the piece is neither silver nor pewter, regardless of its appearance. A slight attraction — not a full stick — can indicate some Britannia metal compositions or solder repairs.

Reliability: High for ruling out ferrous metals; low for distinguishing silver from pewter.

Test 4: Colour and Patina Under Natural Light

Take the piece to a north-facing window or outside on an overcast day for the most neutral light. Sterling silver, when polished, shows a distinctly bright, cool blue-white colour. Pewter, even when polished, carries a warmer, slightly muted grey tone with a subtle blue-grey quality that becomes more pronounced in older, lead-containing antique pieces. Unpolished antique pewter develops a smooth, even grey oxidation; unpolished silver tarnishes unevenly in yellow-brown to black patches.

This test requires experience to use reliably. After examining 20 or 30 pieces the colour difference becomes instinctive, but early on it is genuinely difficult to call. Photograph pieces under consistent lighting and compare with reference examples before drawing conclusions.

Reliability: Moderate — useful as supporting evidence rather than standalone confirmation.

Test 5: The Tarnish and Polish Test

Apply a small amount of standard silver polish (Goddard's or similar) to an inconspicuous spot and work it gently with a soft cloth. Silver responds dramatically: tarnish lifts quickly, the cloth turns black or brown from the silver sulphide removed, and the surface brightens to a high mirror shine. Pewter responds differently. It polishes to a soft, satin-like sheen rather than a mirror finish; the cloth picks up grey-black oxidation rather than the characteristic brown-black tarnish of silver sulphide; and the surface never achieves the same reflective depth as polished silver.

This test is non-destructive when done carefully. Do not use abrasive polishes or apply pressure — pewter scratches more easily than silver, and damage reduces value quickly.

Reliability: High when performed carefully and observed closely.

Test 6: The Ice Cube Thermal Conductivity Test

Silver is one of the best thermal conductors of any element, with a thermal conductivity of approximately 429 W/m·K. Pewter's thermal conductivity is significantly lower, at roughly 35 W/m·K. Place a small ice cube on the flat surface of the piece and watch. On silver, the ice begins melting visibly within seconds because the metal rapidly draws heat from the surrounding air and transfers it to the ice. On pewter, melting is considerably slower.

Run this test at room temperature (approximately 20°C) and avoid pieces that have been sitting in cold storage. It works best on flat surfaces — plates, salvers, or the base of flatware handles — rather than on thick, hollow forms where mass distorts the result.

Reliability: Moderate to high on flat surfaces; less reliable on thick or complex forms.

Test 7: Professional Acid Assay Testing

Acid testing uses nitric acid solutions applied to a small scratch on the metal surface, or to a streak drawn across a black basalt touchstone. Sterling silver at 925 produces a creamy reaction with standard silver acid test solution; base metals and alloys produce different coloured reactions ranging from no reaction to bright green for copper-heavy alloys. Professional assay offices now use X-ray fluorescence (XRF) spectrometry as the modern standard — non-destructive, fast, and accurate to fractions of a percent.

Acid test kits are available from jewellery supply retailers for home use, but the technique requires practice and the acids are corrosive. For any piece you are considering buying above £100, a professional XRF test is a worthwhile investment. The assay offices in Birmingham, Edinburgh, London, and Sheffield all offer testing services to the public.

Reliability: Very high (professional XRF); Moderate (home acid testing with correct technique).

At-Home Test Reliability Summary

Antique Pewter vs Antique Silver: Value and Collectibility

How Much Is Antique Pewter Worth Compared to Silver?

As a general market principle, antique pewter sells for 10–30% of the price of equivalent antique silver. A Georgian silver tankard with clean hallmarks and good provenance might realise £800–1,500 at specialist auction; a comparable pewter tankard from the same period typically sells for £80–300. Condition, maker, rarity, and provenance all move values significantly in either direction.

The intrinsic metal value explains much of the gap. Silver carries commodity value tied to its bullion price (approximately £19–22 per troy ounce at mid-2025 values), while pewter's tin base has minimal commodity value. A silver salver weighing 400 grams carries roughly £150–180 in scrap metal value alone; an equivalent pewter charger has almost no melt value.

When Pewter Items Are Actually More Valuable Than Silver

Certain categories of pewter genuinely command higher prices than comparable silver. Early English pewter — pre-1700 pieces with documented maker's touchmarks traceable to the Pewterers' Company touchplates — can be rare enough to attract serious collector premiums. A documented 17th-century English pewter flagon with a registered touchmark traceable to the 1668 touchplates can sell for more than an equivalent Victorian silver piece with no particular distinction.

American colonial pewter by named makers (William Will, Frederick Bassett, Samuel Danforth) is particularly sought after, with some exceptional pieces exceeding $5,000–10,000 at specialist US auction houses. Guild-marked Continental pewter from Nuremberg, Augsburg, or Amsterdam from the 16th and 17th centuries has its own serious collector market with no silver equivalent at comparable price points.

Red Flags That Suggest a Fake or Misidentified Piece

Watch for these warning signs at estate sales and antique markets: pseudo-hallmarks that look like silver assay marks but lack the specific Lion Passant, date letter, and assay office combination required by law; silver-plated surfaces showing copper or base metal bleeding through at high-wear points such as rims and handles; weight that feels inconsistent with size (too light for claimed silver, too heavy for claimed pewter); and marks struck too shallowly or irregularly to have come from a professional assay office punch.

The sterling silver marks guide provides reference examples of genuine marks versus common imitations, and cross-referencing a suspected date letter against the antique silver date letters database will quickly confirm whether a letter cycle is genuine.

Common Items Mistaken for Silver That Are Actually Pewter

Tankards, Mugs, and Flagons

Tankards represent the single most common category of pewter misidentified as silver at estate sales. English pub tankards, German beer steins, and church flagons all exist in both metals and in identical forms. The handle attachment points on pewter tankards often show slight casting seams invisible on wrought silver; the base rim on pewter pieces is typically less sharply defined than on silver. Run your thumb around the inside base — pewter often shows faint tool marks from the casting process that a raised silver base will not.

Plates, Chargers, and Flatware

Pewter plates and chargers were produced in enormous quantities from the 16th through the 19th centuries and frequently surface in estate lots alongside genuine silver flatware. Feel the rim edge: pewter plates have a slightly softer, more rounded edge than silver, and the plate surface itself shows the characteristic satin finish rather than silver's mirror-like depth. Pewter flatware — spoons in particular — are among the most commonly misidentified items in general antique dealing.

Candlesticks and Decorative Objects

Georgian and Victorian pewter candlesticks closely imitate silver styles, particularly Adam-style column sticks and chamber candlesticks. The weight difference is immediately apparent. Lift one in each hand if you have examples of both materials — the silver piece will feel dramatically denser, and no amount of patina or polish will disguise that.

When to Consult a Professional Hallmark Identifier

Finding a Qualified Assay Office or Appraiser

The four active UK assay offices — London (Goldsmiths' Hall), Birmingham, Edinburgh, and Sheffield — all offer public identification and testing services. Contact details and current fee schedules are available directly from each office. For general appraisal without formal assay testing, a member of the British Antique Dealers' Association (BADA) or the Society of Jewellery Historians with a silver specialisation provides authoritative identification.

For pewter specifically, the Pewter Society maintains a network of specialist members who can assist with touchmark identification, particularly for pieces with unusual or partially legible marks.

What to Bring and What to Expect

Bring the piece clean but unpolished. Do not aggressively polish before appraisal — this removes patina evidence and can damage marks irreparably. Photograph marks before any cleaning at all. A qualified appraiser will examine marks under magnification, assess metal colour and patina, weigh the piece, and may perform a spot acid test or recommend XRF analysis for valuable items. Expect a basic verbal identification to take 15 to 30 minutes; a written appraisal report suitable for insurance or auction purposes requires a formal appointment and carries a fee.

Frequently Asked Questions

How can you tell the difference between pewter and silver?

The fastest and most reliable method is checking for hallmarks. Genuine sterling silver carries a Lion Passant, date letter, and assay office mark, legally required in Britain since 1300. Pewter carries a maker's touchmark or no mark at all. Supporting physical tests — weight comparison, tarnish response, and the ice cube thermal conductivity test — all reinforce the initial mark check.

Does pewter have hallmarks like sterling silver does?

Pewter does not carry legal hallmarks. It carries touchmarks, which are guild-registered maker's marks applied by the craftsman, not verified by an independent assay office. The Worshipful Company of Pewterers maintained touchplate records from 1668, and some touchmarks can be traced through those records, but they carry no legal guarantee of metal content the way a silver hallmark does.

Is pewter heavier or lighter than silver?

Pewter is lighter than silver. Sterling silver has a density of approximately 10.36 g/cm³; pewter sits between 7.0 and 7.5 g/cm³. A pewter tankard and a silver tankard of identical dimensions will feel noticeably different in the hand — the silver piece is roughly 40% denser by volume. Density comparison is one of the most reliable physical tests available without specialist equipment.

Will a magnet stick to pewter or silver?

Neither pewter nor silver is magnetic, so a magnet will not stick to either material. The magnet test is useful for eliminating imposters — electroplated steel, iron-core decorative pieces, or zinc-alloy castings — but it cannot distinguish pewter from silver. Both metals test identically with a magnet, which is why hallmarks, weight, colour, and tarnish response are required for accurate identification.

Why does pewter look so much like silver?

Pewter looks like silver by design. The Worshipful Company of Pewterers, active since 1474, regulated the production of pewter goods specifically intended to serve as affordable substitutes for silverware in ordinary households and taverns. Craftsmen optimised the alloy composition and polishing methods to replicate silver's visual qualities as closely as possible, producing a deliberately similar appearance that has caused identification confusion ever since.
