Silver Hallmarks: The Complete Guide to Identifying Sterling, Plated & Antique Silver Marks

Finding silver at thrift stores, estate sales, and flea markets is one of the most reliable profit plays in reselling. But the distance between a $3 purchase and a $300 sale comes down to one skill: reading hallmarks. The tiny stamps pressed into the metal carry centuries of information about origin, purity, maker, and date—if you know how to decode them.

Most resellers know to flip a piece over and look for “925” or “Sterling.” That gets you started, but it barely scratches the surface. The British hallmarking system alone uses five separate marks that tell you the exact city, year, and silversmith. American silver has its own conventions. Continental European silver carries national purity marks that vary by country. And the most profitable finds—Georgian and early Victorian silver—use coding systems that can date a piece to a single year.

This guide covers everything a reseller needs to identify, authenticate, and price silver using hallmarks in 2026. Whether you’re picking through flatware at Goodwill or evaluating a full tea service at an estate sale, these skills will protect you from fakes and help you spot pieces worth far more than their sticker price.

Why Silver Hallmarks Matter for Resellers

The Knowledge Gap Is Your Profit Margin

Estate sale pricing staff, thrift store employees, and casual sellers rarely know how to read hallmarks. They see “old silver stuff” and price by weight, appearance, or gut feel. A reseller who can identify a Paul Storr hallmark or a Georg Jensen mark in seconds has a structural advantage that doesn’t go away.

Hallmarks Prevent Costly Mistakes

Silver plate looks identical to sterling on the surface. Without hallmark knowledge, you risk paying sterling prices for plated items worth almost nothing in metal value. A full set of silver-plated flatware at an estate sale might cost $50-100 and have a resale ceiling of $30. The same set in sterling could be worth $2,000-5,000. Hallmarks are the only reliable way to know the difference quickly.

Date Marks Drive Premium Pricing

A generic sterling fork might sell for $15-25 to a replacement buyer. The same fork with a Georgian-era date mark (pre-1837) sells to collectors for $80-200+. Older pieces command significant premiums, and date marks embedded in the hallmark system let you verify age without external research.

Maker Marks Unlock Collector Markets

When you can identify a Tiffany & Co. mark, a Georg Jensen mark, or a Paul Revere mark, you’re tapping into collector markets with serious premiums. These aren’t just “old silver”—they’re documented works from recognized silversmiths with auction records and specialized buyers.

Understanding Silver Purity Standards

Before diving into specific marks, understand the purity grades that define silver value.

Sterling Silver (92.5% Pure)

The global standard for quality silver. Sterling contains 925 parts per thousand pure silver, with the remaining 75 parts typically copper for durability.

Common Sterling Marks:

“Sterling” (American standard)
“925” or “.925” (international)
“Ster” (abbreviation)
Lion passant (British)
“Sterling Silver” (full designation)

Coin Silver (90% Pure)

An American standard common from the Colonial period through the mid-1800s. Coin silver was literally made from melted coins and contains 900 parts per thousand silver.

Common Coin Silver Marks:

“Coin” or “C”
“Standard”
“Premium”
“Dollar” or “D”
Often just the maker’s name with no purity mark (pre-1860)

Continental Silver Standards

European countries maintained their own purity standards before standardization:

French First Standard: 950/1000 (higher than sterling)
German 800 Silver: 800/1000 (common in flatware)
Dutch Silver: 833/1000 or 925/1000
Russian Silver: Various zolotniks (84, 88, 91 zolotnik)
Italian Silver: 800/1000 (most common) or 925/1000

Reseller Tip: French and Russian silver in high purity can command premiums above British sterling because collectors value the national hallmark systems and the silver content is often higher.

Silver Plate (Zero Silver Value)

Plated items have a thin layer of silver electroplated over a base metal. The silver content is measured in microns and has essentially no melt value.

Common Silver Plate Marks:

“EPNS” (Electroplated Nickel Silver)
“Silver Plate,” “Plated,” or “A1 Plate”
“Quadruple Plate” or “Triple Plate”
“Rogers” and “1847 Rogers Bros” (plated flatware)
“WM Rogers,” “International Silver” (usually plated)
“Sheffield Plate” (early form, pre-1840, sometimes collectible)
“EPBM” (Electroplated Britannia Metal)

The British Hallmarking System: Five Marks That Tell the Full Story

Britain has the world’s oldest and most comprehensive hallmarking system, dating to 1300. Understanding British hallmarks is essential because enormous quantities of British silver circulate in the American market through estate sales and antique dealers.

Mark 1: The Maker’s Mark

The first mark identifies the silversmith or manufacturing company. Early marks used symbols (a crown, a fish, initials in a shield). By the 18th century, the maker’s mark standardized to the silversmith’s initials in a distinctive shaped surround.

High-Value Maker’s Marks to Know:

PS (Paul Storr, 1792-1838): Premium of 3-10x over generic sterling. Tea sets, centerpieces, and candelabra by Storr regularly sell at auction for $5,000-50,000+.
HB (Hester Bateman, 1761-1790): Highly collected female silversmith. Even small spoons sell for $100-300.
MB (Matthew Boulton, 1773-1809): Important Birmingham silversmith. Candelabra and Sheffield plate pieces are museum-worthy.
PdL (Paul de Lamerie, 1713-1751): The most collected English silversmith. Pieces regularly sell for six figures at auction.

Mark 2: The Standard Mark (Purity)

Indicates the silver content meets the required standard.

Lion Passant (walking lion facing left): Sterling standard (925/1000) used in England since 1544.
Lion Rampant (standing lion): Used in Scotland for sterling.
Hibernia (seated female figure): Used in Dublin for Irish sterling.
Britannia (seated female with trident): Higher standard (958/1000), mandatory 1697-1720, optional afterward.

Mark 3: The Assay Office Mark

Identifies which city tested and certified the silver.

Leopard’s Head (London): The oldest assay office, operating since 1300. Crowned until 1821, uncrowned after.
Anchor (Birmingham): Active since 1773. Enormous quantities of Birmingham silver exist.
Crown (Sheffield): Active since 1773. Known for plate and hollowware.
Castle (Edinburgh): Scottish silver, often commands premiums.
Crowned Harp (Dublin): Irish silver, collected and valuable.

Mark 4: The Date Letter

This is the most powerful mark for resellers. Each assay office used a rotating alphabet of letters in specific fonts and shields to indicate the exact year of manufacture. By cross-referencing the letter style, font, and shield shape with published date-letter tables, you can identify the year a piece was made with certainty.

How to Use Date Letters:

Identify the assay office mark first (city)
Note the letter, its font (roman, italic, gothic, etc.), and the shape of its surround
Consult a date-letter chart for that city
Match all three elements (letter + font + shield shape) to get the year

Example: A piece with the London leopard’s head, a lowercase italic “a” in a shield-shaped surround = 1796. The same “a” in a different font or different shield shape = a completely different year.

Free Resources for Date Letters:

The Online Encyclopedia of Silver Marks has comprehensive date-letter charts
British Museum publishes reference charts
Assay office websites maintain their own date tables

Mark 5: The Duty Mark (Monarch’s Head)

From 1784 to 1890, an additional mark showing the reigning monarch’s profile indicated that duty (tax) had been paid. This mark helps narrow dating:

George III profile (1784-1820)
George IV profile (1820-1830)
William IV profile (1830-1837)
Victoria profile (1837-1890)

After 1890, the duty mark was discontinued.

American Silver Marks: A Different System

American silver marking is less standardized than British but follows recognizable patterns.

Pre-1860: Coin Silver Era

Early American silversmiths usually stamped only their name or initials. Purity marks were inconsistent:

“COIN” meant 90% silver
Many pieces had only the maker’s name
Some used “PURE COIN” or “STANDARD”

Valuable Early American Makers:

Paul Revere Jr. (1735-1818): Pieces sell for $10,000-500,000+ at auction. Even attribution to his shop adds enormous value.
Myer Myers (1723-1795): Colonial New York silversmith. Museum-quality pieces.
Samuel Kirk (1793-1872): Baltimore’s most important silversmith. Kirk repousse patterns remain highly collected.

Post-1860: Sterling Standard

After the Civil War, “STERLING” became the standard American mark. Most reputable manufacturers adopted it. Look for:

“STERLING” stamped clearly
Often accompanied by the maker’s mark and pattern number
Weight marks (in troy ounces) on some pieces

Major American Silver Manufacturers

Tiffany & Co. — Look for “TIFFANY & CO.” with pattern numbers and “STERLING.” Tiffany flatware patterns like Chrysanthemum, Audubon, and Japanese sell for significant premiums. A single Chrysanthemum place setting can bring $300-600.

Gorham — Marked with a lion, anchor, and “G” logo plus “STERLING.” Gorham patterns like Chantilly, Buttercup, and Strasbourg are the most commonly found sterling flatware at estate sales. Replacement demand keeps prices steady at $25-65 per piece depending on pattern and piece type.

Reed & Barton — Eagle mark with “R&B” and “STERLING.” Francis I pattern pieces are among the most valuable American sterling flatware, with serving pieces reaching $200-400.

International Silver — Note: “International Silver” without “STERLING” is almost always plated. Must say “STERLING” explicitly.

Wallace — Look for “WALLACE” with “STERLING.” Grand Baroque pattern is highly collected. Serving pieces run $150-350.

Kirk Stieff — Baltimore manufacturer with distinctive repousse patterns. Kirk Rose and Repousse patterns have devoted collectors. Full sets can bring $3,000-8,000.

Continental European Silver Marks

French Silver

French silver uses a sophisticated mark system:

Minerva Head (large): First standard (950/1000)
Minerva Head (small): Second standard (800/1000)
Maker’s mark in a lozenge (diamond shape)
Pre-1838 marks include a variety of tax stamps and city marks

French silver is often higher purity than British sterling and commands premiums from collectors. Christofle is the most common French silver brand—but note that most Christofle is silver plate, not sterling. Look for the Minerva head to confirm sterling.

German/Austrian Silver

“800” is the most common German silver purity mark
Crescent and Crown: Imperial German silver mark (used pre-1888 and indicates 800+ standard)
Diana Head: Austro-Hungarian silver mark
Look for city marks from major centers: Berlin, Munich, Vienna, Augsburg

German 800 silver is lower purity than sterling but still has significant metal value. Large serving pieces and hollowware are commonly found.

Russian Silver

Russian silver marks are highly collectible and valuable:

84 Zolotnik = 875/1000 (most common Russian standard, close to sterling)
Kokoshnik mark (female head in headdress): Post-1896 Russian assay mark
City marks (Moscow: St. George slaying dragon; St. Petersburg: crossed anchors)
Maker’s marks in Cyrillic

Reseller Alert: Russian silver from the pre-Revolutionary era (before 1917) commands significant premiums from collectors. Fabergé marks are the holy grail—a confirmed Fabergé piece with proper marks can be worth thousands to hundreds of thousands of dollars.

Scandinavian Silver

Georg Jensen (Denmark): Crown over “GJ” in beaded oval, or “Georg Jensen” in oval. Jensen silver commands 3-10x premiums over generic sterling. Even small brooches sell for $100-300. Hollowware pieces reach $1,000-15,000+.
Swedish three-crown mark: Indicates Swedish sterling (830 standard)
Norwegian marks: Lion in shield with “830S” or “925S”

How to Identify Silver in the Field: A Step-by-Step Process

Step 1: Flip the Piece Over

Check the bottom, back, or handle for marks. On flatware, marks are usually on the back of the handle. On hollowware, check the bottom. On jewelry, check clasps, the inside of rings, or tag edges.

Step 2: Use a Loupe or Phone Camera

Silver hallmarks are small—often 2-4mm. A 10x loupe is essential for fieldwork. Alternatively, use your phone camera zoomed in, which can reveal marks invisible to the naked eye. Take photos of all marks for later research.

Step 3: Check for Sterling Indicators

Look for any of these marks: “STERLING,” “925,” “.925,” “STER,” lion passant, Minerva head, or any other national purity mark.

Step 4: Eliminate Silver Plate

If you see “EPNS,” “Plate,” “Plated,” “Silver Plate,” “Rogers Bros,” or “IS” (International Silver) without “Sterling,” the item is plated. Walk away unless the piece has separate decorative or antique value.

Step 5: Identify the Maker

Once you confirm sterling, look up the maker’s mark. Use resources like 925-1000.com for most marks, or specialized references for American makers. The maker determines whether you have commodity sterling or collector-grade silver.

Step 6: Date the Piece

For British silver, use date letters. For American silver, research the manufacturer’s mark variations—most evolved over time, and collectors have documented the changes. Older pieces generally command higher prices.

Step 7: Weigh for Floor Value

Even if you can’t identify the specific piece, knowing the weight gives you the scrap floor. Sterling silver is worth approximately $0.85-0.95 per gram at current spot prices (varies with market). A 100g sterling piece has a floor value of roughly $85-95 in scrap, regardless of maker or pattern.

Use our Flip Profit Calculator to determine if the scrap value alone justifies the purchase price, then research for collector premiums.

Pricing Silver: Scrap vs. Collector vs. Replacement Value

Scrap Value

The absolute minimum a sterling piece is worth, based on silver content by weight.

How to Calculate:

Weigh the piece in grams
Multiply by 0.925 (sterling purity)
Convert to troy ounces (divide by 31.1)
Multiply by current spot silver price

Example: A 200g sterling serving spoon × 0.925 = 185g pure silver ÷ 31.1 = 5.95 troy oz × $30/oz spot = $178.50 scrap value.

Replacement Value

For common flatware patterns, replacement buyers will pay 1.5-3x scrap for pieces they need to complete a set. Sites like Replacements, Ltd. list retail prices; eBay sold listings show actual market prices.

How to Research:

Search the pattern name + piece type on eBay sold listings
Check Replacements.com for retail benchmarks (actual selling prices are usually 40-60% of Replacements retail)
Use our Sold Comps Research Tool for quick cross-platform pricing

Collector Value

For pieces by notable makers, from significant periods, or with unusual designs, collector value can be 3-50x scrap. This is where silver hallmark expertise pays off most dramatically.

Factors That Drive Collector Premiums:

Documented maker (Paul Storr, Georg Jensen, Tiffany, etc.)
Early date (Georgian, Colonial American)
Unusual form (wine funnels, grape scissors, asparagus tongs)
Matching sets with complete provenance
Exceptional condition with crisp hallmarks
Regional significance (Southern American silver, provincial British)

Common Fakes and Reproductions to Watch For

Duty Dodgers

Historical pieces where marks were transposed (cut from a smaller, cheaper piece and soldered into a larger one to avoid higher duty charges). Look for marks that seem too small for the piece, solder evidence around marks, or marks in unusual locations.

Modern Reproductions with Fake Marks

Mass-produced items from Southeast Asia sometimes carry fake British hallmarks. These are usually identifiable by:

Mark quality (fuzzy, poorly struck)
Wrong combinations (date letters that don’t match the assay office)
Inconsistent patina
Weight inconsistency (too light or too heavy for the form)

Sterling-Marked Plate

Some unscrupulous sellers stamp “925” on plated items. Test with an acid testing kit if the piece seems too light or the hallmarks look stamped rather than die-struck. A strong neodymium magnet can also help—sterling silver is not magnetic.

Weighted Sterling

Many candlesticks, console pieces, and compotes are “weighted sterling”—a thin sterling shell filled with plaster, cement, or pitch for stability. The sterling content is a fraction of what the overall weight suggests. Look for:

“WEIGHTED” or “REINFORCED” stamps
Felt or material covering the base
Items that feel too heavy or too light for their size
Seam lines around the base

Reseller Strategy: Where to Find Silver and What to Pay

Estate Sales

The best source for quality silver. Families liquidating estates often have inherited silver they don’t understand the value of. Estate sale sourcing strategies are critical for silver hunting.

Tips:

Check preview photos for silver pieces—most estate sale companies photograph silver but may misprice it
Arrive early and go directly to silver displays
Ask if there’s additional silver not displayed (check kitchen, china cabinets, buffets)
Silver tea services, flatware chests, and trophy pieces often hide the best profit margins

Thrift Stores

Thrift stores occasionally receive silver donations, especially after estate cleanouts. Goodwill and similar chains typically price by appearance rather than metal content.

Where to Check:

Housewares section (flatware, serving pieces)
Jewelry display case (sterling jewelry)
Glass display cases near checkout
Donation staging areas (ask staff about new arrivals)

Online Auctions

eBay, local auction houses, and online-only auction platforms often have silver lots. Research sold comps before bidding to establish maximum bid levels.

Yard Sales and Flea Markets

Lower probability but occasionally yield significant finds. Sellers at yard sales almost never know hallmarks. A polite question like “Do you know if this is real silver?” often gets an honest answer.

Frequently Asked Questions

How can I tell if something is real silver without testing?

Check for hallmarks first—“Sterling,” “925,” or national purity marks like the lion passant confirm sterling silver. If marks are absent or unclear, check the weight (silver is denser than most plated base metals), use a neodymium magnet (silver is not magnetic), and examine wear patterns (plating wears through at edges revealing base metal underneath).

What’s the difference between 800 silver and 925 sterling?

800 silver contains 80% pure silver vs. 92.5% in sterling. German, Italian, and some other Continental European silver commonly uses the 800 standard. While lower in purity, 800 silver still has significant value—roughly 86% of sterling’s melt value per gram. Collector premiums may vary.

Are silver-plated items worth anything to resellers?

Generally, silver plate has minimal resale value for the metal content. However, certain plated items have decorative or antique value: ornate Victorian plate tea services ($50-150 as decorative pieces), elaborate candelabra ($30-100), and items by notable plated manufacturers. But the profit margins are slim compared to sterling.

How do I find out what my silver pattern is called?

For American sterling flatware, turn the piece over and look for the maker’s mark and any pattern number. Search the maker’s name on Replacements.com, which catalogs thousands of patterns. For unmarked or obscure patterns, the Sterling Flatware Fashions book by Tere Hagan is the definitive reference.

What’s the best way to sell sterling silver?

For common flatware patterns, sell as individual pieces or partial sets on eBay to replacement buyers—this almost always beats scrap prices. For collector pieces, consider specialized auction houses (Heritage Auctions, Christie’s, Bonhams) or dealer sales. For damaged or generic pieces, local silver refiners pay closest to spot price. Use our eBay Fee Calculator to model your net proceeds on different platforms.

Can I clean antique silver before selling?

Light cleaning is fine—most buyers expect polished silver. However, don’t use aggressive polishing on pieces with hallmarks, as worn-down hallmarks reduce value. Never use abrasive cleaners on Russian, Georgian, or early American silver. For high-value pieces, let the buyer or a professional conservator decide on cleaning.

How accurate are phone apps for identifying silver?

AI identification apps like Underpriced can help identify common patterns and provide ballpark values, but hallmark reading still requires human expertise and a loupe. Use apps for initial research, then verify with hallmark reference sources.

Building Your Silver Knowledge Over Time

Silver hallmark identification is a skill that compounds. The more marks you see, the faster you recognize them. Start with the basics:

Learn to spot sterling vs. plate instantly — this alone prevents expensive mistakes
Memorize the top 10 American makers — Tiffany, Gorham, Reed & Barton, Wallace, Kirk, International, Towle, Lunt, Alvin, Whiting
Learn the British assay office marks — just four symbols cover most British silver you’ll encounter
Study one date-letter chart — start with London, the most common
Know your Georg Jensen marks — Jensen is the single most valuable Scandinavian maker and frequently appears at US estate sales

Track your silver finds and compare your hallmark reads to confirmed identifications. Within 6 months of active hunting, you’ll be reading marks faster than you can research them. And the resellers who can read hallmarks in the field—while everyone else is pulling out their phones—are the ones who walk out of estate sales with the best silver at the lowest prices.
