Knowing how to tell if silver is real starts with a simple habit: turn the piece over and look before you do anything else. A fork inherited from a grandmother, a candlestick found at an estate sale, a tray that seems unusually heavy: each of these may be solid sterling, silver plate over copper or nickel, or something else entirely. For well over a century our family has handled silver from the great French and Italian maisons, and the question we hear most often is not about value but about identity. What is this piece really made of? This guide walks through the evidence in the order a specialist uses it: first the hallmarks, then the signs that separate sterling from plate, then the home tests and their very real limits, and finally the moment when only a professional assay will give a reliable answer.
What “real silver” actually means
Pure silver is too soft for everyday objects. A spoon of fine silver would bend in a bowl of ice cream, so silversmiths have always alloyed it, usually with copper, to give strength. The purity of the alloy is expressed in parts per thousand, known as millesimal fineness. Sterling silver is 925 parts silver in every thousand, which is why the number 925 appears on so much tableware and jewellery. Britannia silver is finer at 958, and continental European pieces may be marked 800 or, in France, 950.
These numbers are not arbitrary. In the United Kingdom the hallmarking guidance notes published by the Assay Offices list the legal standards for silver as 999, 958, 925 and 800. Anything described as silver in the course of trade must meet one of them and, above a small weight threshold, carry a hallmark to prove it.
Silver plate is a different material altogether. It is a base metal, typically copper, brass or nickel silver, coated with a thin layer of silver by electrolysis. Well-made plate from a house such as Christofle is beautiful and durable, but it is not sterling, and knowing which one you own changes how you clean, insure and use it.
Silver hallmarks: the most reliable evidence you have
A hallmark is a set of small punched symbols that records who made or sent a piece for testing, how pure it is and where it was tested. It is the closest thing silver has to a passport. The British system is the oldest continuous consumer protection scheme of its kind: the Goldsmiths’ Company traces it to a statute of 1300 under Edward I, which required silver to be marked with the leopard’s head before it left the workshop, and the word itself most likely comes from Goldsmiths’ Hall in London.
How to read British sterling silver marks
According to the Goldsmiths’ Company Assay Office, a modern UK hallmark has three compulsory marks: the sponsor’s mark (usually initials in a shield, identifying the maker or importer), the millesimal fineness mark (such as 925 in a distinctive shaped cartouche) and the assay office mark. Two further marks are optional but very common on British silver: the date letter, which changes each year, and a traditional fineness symbol, such as the lion passant for sterling or the figure of Britannia for 958 silver.
The assay office mark tells you where the piece was tested. Four offices operate today:
- London: the leopard’s head.
- Birmingham: the anchor, used by the Birmingham Assay Office since its foundation in 1773.
- Sheffield: the rose, which replaced the earlier crown.
- Edinburgh: the castle.
Older British silver may show marks from offices that have since closed, such as Chester or Exeter, and Victorian pieces often carry a sovereign’s head duty mark. A full, crisp set of marks in a neat line is a strong indicator of genuine sterling.
The French Minerva head
French silver uses a different vocabulary. Since 1838 the guarantee mark for larger silver objects has been the profile of Minerva, the Roman goddess, wearing a helmet. A small number 1 near her face signals the first standard of 950 parts per thousand, which is finer than British sterling; a number 2 indicates the second standard of 800. The Minerva head is struck alongside a lozenge-shaped maker’s mark, the lozenge being characteristic of French solid silver. Pieces from Puiforcat, whose history we explore in our article on the art of crafting silver, typically show exactly this pairing. Silver-plated French pieces, by contrast, usually carry a square or rectangular maker’s mark and no Minerva.
Italian silver marks
Italian silver is normally stamped with its fineness in numbers, most often 925 or 800, together with an identification mark: a polygon containing a star, a registration number and the abbreviation of the province where the maker is registered, for instance MI for Milan, FI for Florence or VI for Vicenza. The combination of the fineness number and a complete identification mark is what you are looking for. A lone “925” with no maker identification deserves more caution.
What marks can and cannot tell you
Here is the uncomfortable truth: a stamp is only as honest as the person who struck it. Genuine hallmarks applied by an independent assay office are extremely difficult to fake convincingly, but a simple “925” or “sterling” punched by a manufacturer in a country without compulsory hallmarking is a claim, not a guarantee. American silver, for example, is traditionally marked “Sterling” by the maker rather than by an independent office. Use magnification, a 10x loupe is ideal, and look for sharp edges, consistent depth and marks positioned where they would naturally be struck, such as the back of a fork stem or the underside of a tray.
Sterling silver vs silver plate: telling them apart
Plated silver has its own marking language, and it is often more candid than people expect. The initials EPNS mean electroplated nickel silver, a base alloy of copper, nickel and zinc that contains no silver at all under the plating. EPBM means electroplated Britannia metal, a pewter-like alloy. Other common indicators include “A1”, “EP”, “silver plate”, “Sheffield plate” on later reproductions, and numbers such as 90 or 100 stamped on continental flatware, which refer to grams of silver deposited per dozen pieces rather than to fineness.
Beyond the marks, look for physical clues:
- Wear: on plate, the high points such as the tips of spoons or the edges of a tray may show a coppery or yellowish base metal beneath.
- Weight: sterling is dense and feels substantial; plated pieces on a nickel silver base can be equally heavy, so weight alone proves little.
- Construction: hollow handles on knives are normal for both sterling and plate, so check the blade and ferrule marks rather than the handle.
- Colour: fine sterling has a soft, warm white lustre; heavily worn plate can look slightly grey or bluish.
If you are building or completing a service, understanding this distinction matters for care as well as value. Our collector’s guide to sterling silver flatware sets explains how solid and plated cutlery differ in weight, patina and longevity.
Home tests for 925 silver, and their limits
When there is no mark, or the mark is worn beyond reading, people naturally turn to home tests. Some are useful as a first filter. None is conclusive, and a few can damage a piece irreparably. Think of them as ways to rule something out rather than to prove it genuine.
The magnet test
Silver is not magnetic. If a strong neodymium magnet snaps firmly onto a piece, it almost certainly has an iron or steel core. The limitation is obvious once stated: copper, brass, nickel silver, aluminium and many other metals used in fakes and in plate are not magnetic either. A piece that ignores the magnet has passed a very low bar.
The ice test
Silver conducts heat exceptionally well. Place an ice cube on a flat silver surface, such as a tray or the bowl of a spoon, and it should begin melting almost at once, faster than on a stainless steel spoon beside it. It is a charming demonstration, but copper is also an excellent conductor, and a plated piece on a copper base can behave very similarly.
The tarnish and cloth test
Real silver reacts with sulphur compounds in the air and darkens over time. Rub an inconspicuous area with a soft white cloth: black marks on the cloth suggest silver oxidation. Unfortunately silver plate tarnishes in exactly the same way, because its surface is silver, and some base metals also leave dark residue. The absence of tarnish is not proof of a fake either, since lacquered or rhodium-finished pieces resist it.
The smell test
Sterling silver has virtually no smell. Rub the piece briskly between your hands and sniff: a sharp metallic odour, the kind associated with coins or brass door handles, points to copper or brass close to the surface. It is subjective and easily confused, but it can raise a useful question about an unmarked item.
Tests to avoid on anything you value
Acid testing kits, bleach tests and scratching into the metal all appear in online advice. They work by removing or corroding a small area of the surface, which on an antique means permanent damage, and on a plated piece means cutting straight through to the base metal. On heirloom silver, leave these to a professional who can test discreetly where it will never show.
When to use a professional assay
There comes a point where the only honest answer is that you do not know, and that is a perfectly respectable place to be. A professional assessment makes sense when a piece is unmarked or has marks you cannot identify, when you intend to sell, insure or divide an estate, when the marks look suspiciously crisp on a supposedly old object, or when a set contains mixed pieces that may have been matched over the years.
Modern laboratories and assay offices use X-ray fluorescence (XRF), which reads the surface composition of the metal in seconds without damaging it. Because XRF measures the surface, a skilled tester will interpret the result carefully for plated items. For the most precise results, a fire assay removes a tiny sample and measures the silver content chemically; it is the reference method used to verify fineness. The UK assay offices also offer services to identify and trace existing hallmarks, which can be invaluable for dating a piece and confirming its maker.
In our own experience advising clients, the most common surprise is not a fake but a misunderstanding: a service believed to be sterling that turns out to be high-quality plate, or an unassuming set of Italian spoons that proves to be 800 silver from a respected workshop. Both are good outcomes, because both let the owner care for the pieces correctly.
Caring for silver once you know what it is
Identification is not just academic. Sterling can be polished many times over generations, while plate has a finite layer of silver that aggressive polishing will eventually wear through. Both dislike rubber bands, salt, eggs and prolonged contact with acidic foods, and both are best stored in anti-tarnish cloth. Our step-by-step guide on how to clean silver cutlery without damaging it covers the gentle methods we recommend for both sterling and plated flatware.
Key takeaways
The most reliable way to identify real silver is to read its hallmarks. A full British hallmark includes a sponsor’s mark, a millesimal fineness mark such as 925 and an assay office mark (the leopard’s head for London, the anchor for Birmingham, the rose for Sheffield, the castle for Edinburgh), often with a date letter and the lion passant for sterling. French solid silver carries the Minerva head, with 1 for 950 and 2 for 800, next to a lozenge-shaped maker’s mark. Italian silver shows a fineness number with an identification mark containing a star, a number and a province code. Marks such as EPNS, EPBM, EP or A1 indicate silver plate. Home tests (magnet, ice, tarnish, smell) can help rule out obvious fakes but cannot prove a piece is sterling, because plated and copper-based items often behave similarly. Avoid acid, bleach and scratch tests on valued pieces. For unmarked items, sales, insurance or estates, a professional XRF test or fire assay gives a definitive answer.
Frequently asked questions about how to tell if silver is real
What does 925 mean on silver?
925 means the metal contains 925 parts of silver per thousand, or 92.5 percent, which is the sterling standard. The remaining 7.5 percent is usually copper, added for strength. On its own a 925 stamp is a manufacturer’s claim; when it is part of an independent hallmark with an assay office mark, it is a legal guarantee.
Does real silver stick to a magnet?
No, real silver is not magnetic. If a magnet sticks strongly, the piece contains iron or steel and is not solid silver. However, many non-silver metals such as copper, brass and nickel silver are also non-magnetic, so passing the magnet test does not prove a piece is genuine.
How can you tell sterling silver from silver plate?
Check the marks first: sterling carries a fineness mark such as 925, sterling or a lion passant, while plate is often marked EPNS, EPBM, EP or A1. Also look for wear on high points, where plated pieces may reveal a yellowish or coppery base metal under the silver layer.
Does fake silver tarnish?
Silver plate tarnishes just like sterling because its surface is real silver, and some base metals also discolour. Tarnish therefore shows that silver or a reactive metal is present at the surface, but it does not confirm that the whole piece is solid silver.
Where can I get silver tested professionally?
Assay offices, accredited testing laboratories and experienced silver specialists can test silver using non-destructive X-ray fluorescence or, for the highest precision, a fire assay. In the United Kingdom the assay offices in London, Birmingham, Sheffield and Edinburgh also help identify existing hallmarks.
Buying and keeping silver with confidence
Real silver rarely hides its identity from someone who knows where to look. Read the marks under good light, use home tests only to rule out the obvious, and turn to a professional whenever the answer genuinely matters. The best protection of all is to buy from an authorised retailer that can tell you exactly who made each piece and to what standard.
