You inherited a set of silverware or picked up a piece at an estate sale, and now you’re wondering: is this real silver or just silver plated? The difference matters enormously. A sterling silver flatware set for 12 can be worth $1,200 to $4,500. A silver-plated set in the same pattern is worth $20 to $80 for the metal alone.
This guide explains exactly what distinguishes sterling silver from silver plate and coin silver, how to test any piece at home without damaging it, how to read every hallmark you might encounter, what your silver is actually worth today, and where to sell it for the best return.
What Is Sterling Silver?
Sterling silver is a metal alloy that is 92.5% pure silver and 7.5% other metals, typically copper. The copper is added because pure silver is too soft for practical use — it dents, bends, and scratches easily. The 92.5% purity standard has been used since the 13th century in England and remains the global benchmark today.
When you see .925, 925, STERLING, or the British lion passant stamp on a piece, you are looking at sterling silver. These marks are legally regulated guarantees of silver content. In the United States, it is a federal crime to mark a non-sterling piece as STERLING.
Common sterling silver items include flatware sets, hollowware (bowls, trays, pitchers), jewelry, tea services, and decorative objects. Sterling is a solid silver alloy all the way through — not a coating over another metal.
What Is Silver Plate?
Silver-plated items are base metal objects — usually copper, brass, or nickel silver (an alloy of copper, zinc, and nickel with no actual silver) — covered with a thin layer of real silver applied through electroplating. The silver layer is typically 0.001 to 0.005 inches thick. Underneath that layer is an entirely different metal.
Silver plate was developed in the 1840s as an affordable alternative to sterling. Major manufacturers like Rogers Bros., Community Plate, William Rogers, Oneida, and International Silver produced enormous quantities of silver-plated flatware and hollowware throughout the late 19th and 20th centuries. These pieces have value as decorative and functional objects, but almost none as scrap metal.
When the plating wears through — which typically happens at high-contact points like the backs of spoon bowls and fork tines — the piece reveals the warm copper or yellowish brass beneath and has little monetary value.
What Is Coin Silver?
Coin silver is a third category that confuses many collectors. American silversmiths working before 1868 had no access to a standardized silver supply, so they melted down silver coins to use as raw material. U.S. silver coins of the era were 90% pure silver, which is what gave coin silver its purity and its name.
Coin silver pieces are marked COIN, PURE COIN, DOLLAR, or C in a shaped cartouche. Some pieces from this era carry only the maker’s name or initials with no purity mark at all, which is a dating clue in itself.
Coin silver is real silver with real scrap value — roughly 97% of the value of sterling by weight (90/92.5 = 97.3%). But its primary value is historical and collector-based. Early American coin silver from documented silversmiths, particularly from Boston, Philadelphia, and New York, is highly collectible and commands strong prices at auction regardless of melt value.
Sterling Silver vs Silver Plate: Key Differences at a Glance
| Feature | Sterling Silver | Silver Plate | Coin Silver |
|---|---|---|---|
| Silver content | 92.5% throughout | Thin coating only | 90% throughout |
| Hallmark | 925, STERLING, or lion passant | EPNS, A1, Rogers Bros., brand + PLATE | COIN, PURE COIN, DOLLAR, or C |
| Scrap value | Significant (weight × 0.925 × spot price) | Near zero | Significant (weight × 0.90 × spot price) |
| Era (American) | 1868–present | 1840s–present | Pre-1868 |
| Wear pattern | Tarnishes evenly, no color change through | Reveals copper or brass when plating wears | Tarnishes evenly like sterling |
| Weight | Heavier than plated equivalent | Lighter, thinner gauge | Similar to sterling |
| Collector value | High (maker premiums for Gorham, Tiffany) | Moderate (pattern and condition) | High (historical and regional maker premiums) |
How to Tell If Silver Is Real: 6 Tests You Can Do at Home
1. The Hallmark Test (Most Reliable)
Turn the piece over and look for stamps with a magnifying glass. Sterling silver will be marked with one of these:
- 925 or .925 — the international purity mark
- STERLING — the American standard mark
- Lion passant — the British sterling mark (a walking lion)
- 800 or 835 — European silver standards (lower purity than sterling, but still real silver)
- COIN, PURE COIN, DOLLAR — early American coin silver (90% pure)
Silver plate marks to recognize:
- EPNS — Electroplated Nickel Silver
- A1, AA, TRIPLE — plating thickness grades
- Silver on Copper, Silver on Brass — base metal identification
- Brand names: Rogers 1847, Community Plate, WM Rogers & Son, International Silver
2. The Magnet Test
Silver is not magnetic. Hold a strong magnet (a neodymium refrigerator magnet works well) near the piece. If it attracts strongly, the base metal is iron or steel and the piece is not sterling. However, this test has limits: copper, brass, and nickel silver are also non-magnetic, so a non-reaction does not confirm sterling — it only rules out iron-based metals.
3. The Ice Test
Silver has the highest thermal conductivity of any metal. Place an ice cube on a flat silver surface. On genuine sterling, the ice will begin melting almost immediately — much faster than on glass, ceramic, or wood. The silver conducts heat from your room so efficiently that the ice melts rapidly on contact. This is a useful quick check but not as definitive as the hallmark or acid test.
4. The Acid Test (Professional Standard)
Silver testing kits are available for $10 to $20 at jewelry supply stores. Apply a small drop of nitric acid to a discreet spot on the piece. The color of the reaction tells you the silver content:
- Bright red or cream — fine or sterling silver
- Dark red to brown — lower-grade silver (800 or 835)
- Green — base metal, copper-based alloy
- Yellow to gold — brass
- No reaction (milky white) — fine silver or heavily plated piece
This test is definitive but leaves a tiny mark. Test on the back of a foot, inside a handle, or on a surface that won’t be visible during display.
5. The Tarnish Pattern Test
Both sterling and silver plate tarnish, but differently. Sterling tarnishes to a uniform dark gray or black. Silver plate that is wearing through shows reddish-copper or yellowish patches where the base metal is exposed. Those warm-toned areas through the tarnish are the definitive sign that a piece is plated.
6. The Weight and Feel Test
Sterling silver flatware feels noticeably heavier and more substantial than silver-plated equivalents in the same pattern. Silver plate is made to lighter gauge standards because the manufacturer’s goal is to minimize the base metal cost. If a piece feels light and thin, it is likely plated. This test works best when you have a known sterling piece to compare against.
Reading Silver Hallmarks
American Marks
American sterling is marked STERLING or 925. There is no government assay office in the United States — marking is done by the manufacturer on the honor system, but the term STERLING is legally defined under the National Stamping Act (1906) and misusing it is fraud. Common American sterling makers include Gorham, Tiffany & Co., Reed & Barton, Towle, Wallace, Kirk Stieff, and Lunt.
British Marks
British silver carries a full set of hallmarks applied by independent government assay offices — the most comprehensive hallmarking system in the world. A complete set includes:
- Maker’s mark — the silversmith’s initials in a shaped cartouche
- Lion passant — the sterling standard mark (England); thistle (Edinburgh); harp (Dublin)
- Assay office mark — leopard’s head (London), anchor (Birmingham), rose (Sheffield), castle (Edinburgh)
- Date letter — a letter in a shaped shield indicating the exact year of assay
- Sovereign’s head — an additional duty mark used 1784–1890 (its presence helps date a piece)
British date letters cycle through the alphabet in different fonts and shield shapes by assay office. Reference guides and online tools like the Online Encyclopedia of Silver Marks can decode any combination.
European Marks
Continental European silver uses numeric purity marks. Common European silver standards:
| Mark | Purity | Countries | Notes |
|---|---|---|---|
| 925 | 92.5% | International | Same as sterling standard |
| 835 | 83.5% | Germany, Netherlands | Common German Jugendstil and Biedermeier silver |
| 830 | 83% | Scandinavia | Norwegian, Danish, and Swedish antique silver |
| 800 | 80% | Germany, Italy, Eastern Europe | Widespread; still real silver but lower purity |
| Minerva head | 92.5% | France (post-1838) | Used instead of numeric mark on French sterling |
| Crescent & crown | 800 | Germany (pre-1888) | Pre-1888 German 800-grade silver mark |
| 84 zolotnik | 87.5% | Imperial Russia | Russian imperial silver standard; 84 in Cyrillic |
| 88 zolotnik | 91.6% | Imperial Russia | Higher Russian standard; rarer |
Sterling Silver Value: What Is It Worth?
Calculating Melt Value
The baseline value of any sterling silver piece is its melt value: the weight of the silver it contains multiplied by the current spot price of silver. To calculate:
- Weigh the piece in troy ounces (1 troy ounce = 31.1 grams)
- Multiply by 0.925 (the sterling purity factor)
- Multiply by the current silver spot price (check Kitco or Apmex for today’s price)
Example: A sterling silver fork weighing 1.5 troy ounces when silver is at $30/oz = 1.5 × 0.925 × $30 = approximately $41.63 in melt value. Dealers typically pay 70 to 90 percent of calculated melt value for scrap silver.
Sterling Flatware Values by Piece
| Piece | Individual Value (common pattern) | Individual Value (premium pattern) |
|---|---|---|
| Dinner fork | $25–$50 | $60–$150 |
| Salad fork | $20–$45 | $50–$120 |
| Dinner knife | $15–$35 | $40–$90 |
| Soup spoon | $20–$45 | $50–$120 |

| Tablespoon / serving spoon | $35–$80 | $90–$250 |
| Butter spreader | $15–$30 | $30–$75 |
| Complete service for 12 (5-piece place setting) | $1,200–$2,500 | $3,000–$8,000+ |
Most Collectible Sterling Flatware Patterns
Some patterns command strong premiums above melt value because of ongoing collector demand. These patterns are worth researching before selling any sterling flatware:
| Pattern | Maker | Introduced | Demand Level | Service-for-12 Range |
|---|---|---|---|---|
| Chantilly | Gorham | 1895 | Very high | $2,500–$6,000 |
| Francis I | Reed & Barton | 1907 | Very high | $3,000–$7,000 |
| Grand Baroque | Wallace | 1941 | Very high | $2,800–$6,500 |
| Chrysanthemum | Tiffany & Co. | 1880 | Extremely high | $8,000–$20,000+ |
| King William | Tiffany & Co. | 1870 | High | $6,000–$15,000+ |
| Repousse | Kirk Stieff | 1828 | High | $2,500–$5,500 |

| Strasbourg | Gorham | 1897 | High | $2,500–$5,000 |
Sterling Hollowware Values
Sterling hollowware (bowls, trays, pitchers, tea services) is valued primarily by weight and maker. Standard market ranges:
| Item | Common Range | Premium Maker Range |
|---|---|---|
| Sterling tea service (4–6 pieces) | $800–$2,500 | $3,000–$15,000+ |
| Sterling serving tray | $200–$800 | $1,000–$5,000 |
| Sterling punch bowl | $500–$2,000 | $3,000–$10,000+ |
| Sterling vegetable dish (covered) | $150–$500 | $500–$2,500 |
| Sterling candlesticks (pair) | $150–$600 | $800–$4,000 |
| Sterling water pitcher | $200–$700 | $800–$5,000 |
| Sterling gravy boat | $100–$300 | $300–$1,500 |
| Sterling bread basket | $100–$350 | $400–$2,000 |
Tiffany & Co. and Georg Jensen pieces carry substantial brand premiums above melt — often 3 to 10 times the metal value. Gorham Martelé (hand-hammered Art Nouveau, 1897–1912) and early American coin silver from documented makers also achieve multiples of melt at auction.

How to Clean Sterling Silver
Sterling silver tarnishes when it reacts with sulfur compounds in the air, forming silver sulfide (the black or dark gray coating). Tarnish is entirely reversible — you are not damaging the silver by letting it tarnish, only by using the wrong cleaning method.
Method 1: Aluminum Foil and Baking Soda Bath (Best for Flatware)
- Line a glass baking dish with aluminum foil, shiny side up
- Place silver pieces in a single layer, each piece touching the foil
- Dissolve 1 tablespoon of baking soda per quart of very hot water
- Pour the solution over the silver until submerged
- The tarnish transfers to the foil through an electrochemical reaction within 2 to 5 minutes
- Rinse thoroughly with clean water and dry immediately with a soft lint-free cloth
This method works because the aluminum acts as a sacrificial anode — the silver sulfide tarnish prefers the aluminum and transfers off the silver. No abrasion, no material removed from the surface.
Method 2: Commercial Silver Polish
Products like Wright’s Silver Cream, Goddard’s Silver Dip, or Hagerty Silver Foam remove tarnish through a combination of mild abrasive and chemical action. Apply with a soft cloth, work in straight lines (circular motions show scratches), rinse well, and dry completely. These are good for ornate pieces with detail that the bath method can miss.
What NOT to Do
- No dishwasher — heat and detergents damage the surface and loosen handles on hollow-handled pieces
- No toothpaste — too abrasive; scratches accumulate and reduce value
- No rubber bands or rubber gloves — rubber accelerates tarnishing through sulfur off-gassing
- No plastic bags — some plastics off-gas sulfur compounds
- No bleach-based cleaners — cause pitting in sterling
Storing Sterling Silver
Proper storage dramatically reduces cleaning frequency. Use anti-tarnish cloth rolls, bags, or chest liners designed for silver. Add a piece of chalk or a silica gel packet to absorb moisture and sulfur. Store flatware in a flannel-lined chest. Keep silver away from rubber, wool, and sulfur-containing foods (eggs, onions, mayonnaise). A piece stored properly in an anti-tarnish chest may not need polishing for years.
Where to Sell Sterling Silver
| Venue | Best For | Price Received | Notes |
|---|---|---|---|
| eBay | Complete flatware sets in popular patterns | 100–150% of melt for good patterns | Largest collector buyer pool; requires photos and effort |
| Replacements.com | Individual pieces in active patterns | 40–80% of retail | Instant buy quotes for pieces they need; less for overstock patterns |
| Heritage Auctions / Skinner / Doyle | Tiffany, Georg Jensen, Gorham Martelé, important hollowware | Varies widely; often best for premium pieces | 15–25% buyer’s premium; seller’s commission applies |
| Local estate dealers / silver dealers | Quick bulk liquidation | 70–85% of melt value | Fast, no effort, competitive melt pricing |
| Silver refiners | Damaged, incomplete, or pattern-less pieces | 80–90% of melt value | Best for scrap; no collector premium |
| Etsy / Ruby Lane | Decorative hollowware, small collectibles | Market rate | Slower sales; niche collector audience |
| Pawn shops | Emergency cash only | 50–60% of melt | Avoid for anything with collector value |
The cardinal rule: never sell a complete flatware set in a popular pattern to a scrap dealer. The collector premium for a complete Gorham Chantilly service for 12 can be 3 to 5 times the melt value — the difference between $800 and $4,000 for the same silver.
Frequently Asked Questions
How do I know if my silverware is sterling or silver plated?
Flip the piece over and look for marks with a magnifying glass. STERLING, 925, or .925 confirms sterling silver. Marks like EPNS, A1, TRIPLE, Rogers Bros., Community Plate, or any brand name followed by the word “plate” indicate silver plate. The hallmark test is definitive. If there are no marks at all, assume silver plate and confirm with a silver acid test kit ($10 to $20 at a jewelry supply store).
What does 925 mean on silver?
925 is the international purity mark for sterling silver, indicating the piece is 92.5% pure silver and 7.5% other metals (typically copper). You may see it stamped as 925, .925, or S925. It is the same standard as the STERLING mark used in the United States and the lion passant mark used in Britain.
What is coin silver and how is it different from sterling?
Coin silver is 90% pure silver (versus 92.5% for sterling), made by American silversmiths before 1868 who melted down silver coins as their raw material. Coin silver pieces are marked COIN, PURE COIN, DOLLAR, or C in a cartouche. It is real silver and has scrap value (about 97% of sterling by weight), and early American coin silver pieces from known silversmiths are highly collectible.
Is sterling silver a good investment?
Sterling silver holds its melt value, which tracks the silver spot price. A complete flatware service for 12 in a popular pattern (Gorham Chantilly, Reed & Barton Francis I, Wallace Grand Baroque) can outperform melt value when sold to collectors. Tiffany and Georg Jensen pieces carry the strongest brand premiums, sometimes selling for 3 to 10 times melt. Common patterns and damaged pieces typically sell at or below melt.
How much is sterling silver worth per ounce?
Sterling silver melt value equals the current silver spot price multiplied by 0.925 (the purity). When silver trades at $30 per troy ounce, sterling is worth about $27.75 per troy ounce in metal alone. Dealers typically pay 70 to 90 percent of spot for scrap sterling. A full sterling flatware service for 12 (five-piece place settings plus serving pieces) often weighs 80 to 120 troy ounces, giving a melt value of roughly $2,200 to $3,300 at $30/oz silver.
Does sterling silver turn green or cause skin reactions?
Sterling silver does not typically turn green or cause skin reactions. The 7.5% copper in sterling can occasionally cause a faint greenish mark on very sensitive skin, but this is uncommon. Silver plate over a copper or brass base is far more likely to cause green discoloration because as the thin silver layer wears through, you are in direct contact with the base metal.
What is the best way to clean sterling silver?
For flatware, the aluminum foil and baking soda bath is the safest and most effective method: line a glass dish with aluminum foil (shiny side up), lay the silver pieces touching the foil, dissolve one tablespoon of baking soda per quart of very hot water, pour over the silver, and let it sit 2 to 5 minutes. The tarnish transfers to the foil through an electrochemical reaction. Rinse thoroughly and dry immediately with a soft cloth. Never use the dishwasher, abrasive scrubbers, or toothpaste on sterling.
Where is the best place to sell sterling silver?
The best venue depends on the piece. Complete flatware sets in popular patterns sell best on eBay (largest buyer pool) or Replacements.com (specialist buyers). Tiffany, Georg Jensen, and high-end hollowware consign well to auction houses like Heritage, Skinner, or Doyle. Local estate dealers and refiners pay melt value or slightly above and are the fastest option for bulk lots. Avoid pawn shops, which typically pay 50 to 60 percent of melt.
