How can I tell if my silver piece is real sterling vs silver plate?

Sterling silver is solid silver alloy throughout. Silver plate is a thin layer of silver electroplated over a base metal (typically nickel silver, white metal, or copper). Key indicators: (1) Stamp inspection — sterling will be stamped STERLING, 925, or have country hallmarks; silver plate is typically stamped EPNS (electroplated nickel silver), EP, A1, EPBM, or similar. (2) Weight — sterling is significantly heavier than silver plate for the same volume. (3) Sound — sterling has a higher pitched ring when tapped; silver plate has a duller sound. (4) Age and wear — silver plate often shows brass or copper undertones at high-wear edges where the plating has worn through, while sterling remains uniform silver throughout. We test every silver piece in the showroom with magnet, acid, and XRF to confirm composition.

Antique Silver Identification Guide: Makers, Hallmarks & Date Letters Decoded

Q: What is antique silver?

Antique silver generally refers to silver objects 100 years old or older. The category includes hollowware (tea sets, trays, candlesticks, bowls), flatware (sterling silver utensil sets), and decorative pieces. Antique silver from established makers (Tiffany, Buccellati, Georg Jensen, Paul Storr, Hester Bateman, Cardeilhac) commands a substantial premium over the underlying silver melt value because of craftsmanship, historical significance, maker reputation, and design. Most American sterling silver from pre-1920 is now antique. English silver from before 1925 is antique by current standards.

Q: What is sterling silver?

Sterling silver is an alloy of 92.5 percent pure silver and 7.5 percent other metals (typically copper) for strength. The 925 fineness standard is recognized internationally and is the American standard for high-quality silver. Sterling pieces are typically stamped 'STERLING,' 'STER,' or '925' on the base. The 7.5 percent copper or other alloy makes the metal hard enough for daily use without significantly affecting the silver content. Other silver standards include Britannia (95.8 percent), Continental 800 (80 percent, common in Italy, Germany, Austria), and pure silver 999 (very rare in flatware due to softness).

Q: What is a maker's mark and how do I find it?

A maker's mark is a symbol, initial, or word stamped onto the silver piece identifying the silversmith or company that made it. Maker's marks are usually stamped on the underside of a piece, near the base, or on the back of a piece of flatware near the handle. The mark is commonly accompanied by a purity stamp (STERLING, 925, 800) and country/city marks. For example, Tiffany pieces are marked TIFFANY & CO. or T&Co. plus STERLING and often a pattern number. Buccellati pieces are marked BUCCELLATI plus 925 (or 800 for older Italian standard). Georg Jensen pieces have the distinctive 'GEORG JENSEN' or 'GJ' shield mark.

Q: How does the English silver date letter system work?

English silver from 1300 to present has been hallmarked under one of the world's oldest consumer protection systems. Each piece carries multiple marks: a city assay office mark (London leopard's head, Birmingham anchor, Sheffield rose, Edinburgh castle, Dublin harp), a sterling lion (passant) or lion's head erased confirming sterling purity, a date letter (a single letter in a specific font and shield style indicating the year of assay), and the maker's mark. The date letter cycle uses a 20-25 letter sequence per cycle, with each city using a different font and shield combination. With these four marks together, an English silver piece can typically be dated to the exact year and traced to the specific city of assay.

Q: Which antique silver makers are most valuable?

Top-tier makers commanding the highest premiums include: Paul de Lamerie (London, 1688-1751), Hester Bateman (London, 1709-1794), Paul Storr (London, 1771-1844), Tiffany & Co. (NY, 1837-present), Buccellati (Milan, 1919-present), Georg Jensen (Copenhagen, 1866-1935), Christofle (Paris, 1830-present), Puiforcat (Paris, 1820-present), Cardeilhac (Paris, 1804-1951), and Gorham (Providence, 1831-present). For American silver, pre-1900 hollowware by major makers (Gorham, Tiffany, Whiting, Reed & Barton) commands strong collector premiums. For English silver, pieces by Storr, de Lamerie, and Bateman family trade at significant premiums to melt because they are among the most collected smiths in history.

Q: What is the French Minerve mark?

The Minerve mark is the French national silver mark, depicting the head of Minerva (Roman goddess of wisdom) in profile. The mark indicates the silver standard: a number 1 next to Minerva indicates 950 fineness (95 percent pure silver), and a number 2 indicates 800 fineness (80 percent). The Minerve mark has been used continuously since 1838 and is one of the most reliable silver standard indicators in European antique silver. French silver also carries a maker's mark (typically a diamond-shape lozenge with the maker's initials) and an assay city mark.

An antique silver piece’s value lives in the maker’s mark. A Tiffany & Co. tea service is worth a multiple of its melt value. An unsigned silver tea service of similar weight melts for its weight in silver. This guide explains how to read maker’s marks, decode English date letters, identify the major American/English/French/Italian makers, and tell sterling from silver plate.

If you are selling antique silver in Miami, the buyer should be able to identify your maker’s mark on-site, research the current auction comparable, and confirm the silver content via XRF testing in front of you. If a buyer wants to price your antique silver purely by weight, they are melting the maker premium. CJ William prices the maker, period, and condition separately from melt value. See the We Buy Silver in Miami page for the buying process.

Sterling vs Silver Plate (Important First Check)

Before researching maker, confirm the piece is solid silver, not silver plate. Sterling silver is 92.5 percent pure silver alloy throughout. Silver plate is a thin layer of silver electroplated over a base metal (nickel silver, white metal, or copper). Silver plate has melt value only when scrap; antique sterling has maker premium PLUS melt value.

Sterling stamps: STERLING, STER, 925, or country hallmarks (lion passant, Minerve, etc.)
Silver plate stamps: EPNS (electroplated nickel silver), EP, A1, EPBM, “Sheffield plate” (a misleading marketing term, NOT sterling), “Silver on copper”
No stamp at all: Generally either silver plate or unmarked sterling, requires XRF or acid test
Weight: Sterling is significantly heavier than plate for the same volume
Wear pattern: Silver plate often shows brass or copper undertones at high-wear edges; sterling stays uniform silver throughout

Silver Purity Standards (International)

Standard	Fineness	Where Common
Britannia	958 (95.8% pure)	English silver, primarily 1697-1720
Sterling	925 (92.5% pure)	Standard for US, UK, and international fine silver
Mexican 950	950 (95% pure)	Mexican silver, often with eagle mark
Continental 900	900 (90% pure)	Older Italian, Russian, some German
Continental 800	800 (80% pure)	Common in Italy, Germany, Austria, Hungary
Coin Silver	900 (US) or 833 (Northern Europe)	Pre-1860s American silver melted from coins

For antique silver from Tiffany, Gorham, Reed & Barton, and most American makers, you’ll see STERLING or 925 stamping. For Buccellati and Italian silver, you’ll see either 925 or 800. For Georg Jensen and Scandinavian silver, you’ll see 925S or “Sterling Denmark.” For French silver, look for the Minerve head with a number 1 (950) or number 2 (800).

How to Find and Read Maker’s Marks

Maker’s marks are typically located:

Hollowware (tea sets, trays, bowls, candlesticks): Stamped on the underside of the base, often along with weight, pattern number, and purity stamp
Flatware (forks, spoons, knives): Stamped on the back of the handle near the bowl/tines, or on the underside of the handle
Decorative pieces: Stamped on the base, the inside of a cover, or hidden in a discreet location

Use a 10x loupe or jeweler’s magnifier to read the mark clearly. Smaller pieces and early-period marks can be very faint. Photograph the marks under bright light with the loupe held over the camera lens for reference.

Major American Silver Makers

Major English Silver Makers

English silver is the most thoroughly hallmarked in the world. Every piece (with rare exceptions) carries four marks: maker, sterling lion, city assay office, and date letter. The most valuable English makers:

Paul de Lamerie (London, 1688-1751) — Mark: PL or P.L. — The most valuable English silversmith, peerless rococo work, museum-tier pieces.
Paul Storr (London, 1771-1844) — Mark: PS in a script cartouche — Master silversmith for Rundell & Bridge, royal commissions.
Hester Bateman (London, 1709-1794) — Mark: HB — Early female master, exquisite Georgian work.
Peter and Ann Bateman / William Bateman — Hester’s family continued the tradition into the 19th century.
Hennell family (London, multi-generational) — Various marks across three centuries.
Garrard & Co. (London, 1735+) — Royal jewellers, distinctive marks.

English Assay Office Marks

London: Leopard’s head (uncrowned post-1820, crowned earlier)
Birmingham: Anchor
Sheffield: Rose (or crown until 1974)
Edinburgh: Castle (and historic thistle for Scotland)
Glasgow: Tree, bird, fish (no longer active)
Dublin: Crowned harp
Newcastle: Three castles (no longer active)
Chester: Three wheat sheaves with sword (no longer active)
York: Five lions on a cross (no longer active)
Exeter: Castle (no longer active)

English Date Letters

Each assay office uses a 20-25 letter alphabetical sequence per cycle, with each year represented by a single letter in a specific font/cartouche combination. The date letter changes annually on a fixed date (May 29 for London historically). Pocket reference guides for date letters by city are available — bring your piece to CJ William and we’ll date it to the year. The combination of all four marks identifies the piece definitively.

Major Italian Silver Makers

Buccellati (Milan, 1919) — Mark: BUCCELLATI + 925 or 800 + maker’s lozenge — Distinctive hand-engraved textured surfaces (“rigato,” “telato,” “ornato” engravings) — the most identifiable Italian silver style.
Mario Buccellati / Gianmaria Buccellati / Federico Buccellati — Various Buccellati family pieces command different premiums.
Brandimarte (Florence) — Modernist Italian work, marked BRANDIMARTE.
Italian provincial silver — Carries an oval lozenge maker’s mark plus province code numerals plus 800 or 925 standard mark.

Major French Silver Makers

Christofle (Paris, 1830) — Mark: CHRISTOFLE + Minerve mark — World’s largest silver producer, ranges from silver plate to fine 950.
Puiforcat (Paris, 1820) — Mark: PUIFORCAT + Minerve — Art Deco and Modernist sterling, highly collected.
Cardeilhac (Paris, 1804-1951) — Mark: CARDEILHAC + Minerve — Acquired by Christofle in 1951.
Odiot (Paris, 1690+) — Mark: ODIOT + Minerve — Royal commissions, museum-tier work.
Aucoc (Paris) — Marked AUCOC, refined Belle Epoque work.

Scandinavian Silver Makers

Georg Jensen (Copenhagen, 1866-1935) — Mark: GEORG JENSEN in a shield or oval, often with “DENMARK” + 925S — Iconic modernist design, internationally collected.
Henning Koppel for Georg Jensen — Specific designer marks within Jensen workshop add value.
Hans Hansen (Denmark) — Marked HANS HANSEN + 925, acquired by Jensen in 1992.

Why Antique Silver Commands a Premium Over Melt Value

A complete Tiffany sterling tea service from the 1880s might contain 200 troy ounces of silver. At current spot price (~$30/oz), the melt value is approximately $6,000. The collector market price for the same Tiffany set in good condition is typically $15,000 to $40,000 — a 2.5x to 6.6x premium over melt. The premium comes from:

Maker reputation (Tiffany sells)
Pattern and design (some patterns are far more collected)
Period (Aesthetic Movement, Art Nouveau, Art Deco each have collector premiums)
Completeness (full services worth more than partial sets)
Original condition (original finish, no monogram removal or polishing damage)
Provenance (notable previous owner adds value)
Original boxes and certificates (presentation pieces add value)

A buyer who weighs your antique silver and offers melt value is treating Paul Storr and a generic Walmart fork the same. CJ William prices each piece based on the maker, period, pattern, condition, and provenance separately from melt value, with each component shown.
