Sterling silver
Reading Silver Hallmarks
A hallmark is a claim, not a guarantee. It tells you what a maker or an assay office said about a piece of silver at the moment it was tested and stamped, and in most cases that claim holds up. But marks wear away, pieces get repaired with mismatched parts, and marks are sometimes faked outright on pieces meant to pass as older or better than they are. Reading marks well means learning the general systems well enough to know what a genuine mark should look like, then checking anything that matters against a real reference rather than trusting memory.
This page explains those systems conceptually, British assay marking, the simpler American approach, and continental purity numbers, and shows where to find a mark and how to read what it is telling you. It does not include a table of date letters or a list of maker's marks, because those details are specific to a country, an assay office, and often a single year, and reproducing them from memory risks getting a real piece wrong. Once you have narrowed down what kind of mark you are looking at, confirm it in a recognized reference such as Jackson's guide to English goldsmiths and their marks, or a reputable hallmark database.
Finding the mark
Start by finding where a mark would be struck. On flatware it is usually on the back of the handle, near the base of the bowl on a spoon or close to the neck on a fork. On holloware, teapots, bowls, trays, look on the underside or base, and check more than one section if a lid or handle might have been tested separately. Use a loupe or a strong light held at a low angle, since marks are often small, shallow, and worn smooth by decades of polishing. Photograph a mark straight on and enlarge the photo rather than relying on the naked eye, especially on jewelry-scale pieces.
How British hallmarking works
British silver has one of the oldest and most consistent marking systems anywhere, and it is built from several small stamps struck together rather than one single mark. A standard mark, most familiar as the walking lion known as the lion passant, indicates sterling purity. A town mark identifies the assay office that tested the piece, historically London, Birmingham, Sheffield, and others, each with its own symbol. A date letter, a single letter in a particular typeface and shield shape, narrows the piece to a specific year within a cycle, and a maker's mark, usually two or three initials in a shield, identifies the person or firm that submitted it for testing.
In certain periods a sovereign's head duty mark was added to show that tax had been paid, which is itself a rough dating clue when it is present or absent. The exact letter forms, shield shapes, and office symbols changed over time and repeat in cycles, which is exactly why this page will not attempt to reproduce them. A specific date letter only means something once you know which office and which cycle it belongs to, and getting that wrong from memory is an easy way to misdate a piece by decades. Look the full combination up in Jackson's or a comparable reference rather than guessing at a year.
American silver: STERLING, 925, and coin
American silver marking is less elaborate than the British system. Most sterling made in the United States from the later nineteenth century onward is stamped STERLING, sometimes alongside 925, the purity expressed as parts per thousand, and usually a maker's name or trademark rather than a coded symbol. Older American silver, generally from before sterling became the standard, is often called coin silver because it was frequently melted from coinage, and it runs close to 90% pure. Coin silver may carry the word COIN, but it is just as often marked only with a maker's initials, a full name, or a simple pseudo-mark meant to look official, with no purity figure stated at all. A piece with no mark whatsoever is not automatically plate. It may be unmarked sterling or coin silver from a maker who simply never stamped it, which is one more reason weight and testing matter alongside the mark itself.
Continental and other purity marks
Outside Britain and the United States, silver purity is commonly expressed as a decimal or a number out of a thousand rather than a word like sterling. Marks such as .800 or .900 are typical of continental European silver, and the exact number, along with any accompanying symbols, again points to a specific country and period best confirmed in a dedicated reference rather than assumed from the shape of the stamp. Treat any three-digit purity number the way you would treat STERLING, as a starting claim worth checking against the piece's weight, wear, and, where it genuinely matters, a specialist's opinion.
When a mark cannot be trusted
Marks can be worn past legibility by generations of polishing, especially on pieces used daily rather than kept for display. They can also be missing because a piece was legitimately never marked, or because a repair replaced the marked section, a new spout or handle, for instance, with unmarked metal. And marks are sometimes faked, struck onto plated or lower-purity pieces to make them pass as something better. None of this is common enough to treat every mark as suspect, but it happens often enough that a mark alone should not settle a question that actually matters, whether that is authenticity, origin, or value.
When the stakes are real, pair the mark with a magnet test, a weight check, and, for anything valuable, a second opinion from someone who handles silver professionally. For how marks and weight fit into the bigger question of what a piece is worth, see the overview of sterling and antique silver.
Mark identification here is educational, not a certification of authenticity or origin. Marks can be worn, altered, or faked, and reading them correctly often depends on details specific to a country and era. For a piece where authenticity or origin matters, confirm the mark in a recognized reference such as Jackson's or a reputable hallmark database, or consult a specialist.
Common questions
Can I date a piece of silver exactly from its hallmark?
Often yes for British silver, since a genuine date letter combined with the correct assay office narrows a piece to a specific year. American and continental marks usually indicate a purity standard and a maker rather than a year. In every case, confirm the reading against a recognized reference before treating the date as settled.
What does it mean if I can't find any mark at all?
An absent mark does not by itself mean a piece is plate. It can also mean coin silver from a maker who never stamped it, a mark worn away by decades of polishing, or a section replaced during a repair. Weight, wear patterns, and a magnet test help narrow it down, and a specialist can usually settle a piece that matters.
