The Four Marks
How to read English silver hallmarks
English silver is the most thoroughly documented silver in the world. For more than 700 years, British silversmiths have been required to bring their finished work to a city assay office for testing, and every approved piece has been stamped with a set of standardized marks. If you have inherited English silver, those marks will tell you almost everything you need to know — the maker, the city, the year, and the precious metal content.
The lion passant — confirmation of sterling
The lion passant is the heart of the English hallmarking system. It is a small image of a lion walking to the left with the right forepaw raised — "passant" means walking in heraldic terminology. When you see the lion passant on an English piece, you are looking at a guarantee that the silver meets the sterling standard of 925 parts per 1000 (92.5% pure). The lion has appeared in this form since 1544 and remains the mark of sterling today.
Pieces at the higher Britannia standard (95.8% pure) carry a different mark — a seated figure of Britannia — instead of the lion passant. Britannia silver was mandatory from 1697 to 1720 and has remained available as an optional higher standard ever since. Most English silver you will encounter is sterling, marked with the lion.
Assay office town marks
Each English assay office has its own town mark, which appears on every piece assayed there. These are the main ones you will encounter on inherited silver:
London — leopard's head. The oldest English assay office, in continuous operation since 1300. The leopard's head was crowned until 1822 and uncrowned thereafter. London marks are the most common on fine English silver.
Birmingham — anchor. Opened in 1773 to serve the booming Midlands silver trade. Many everyday and mid-range Victorian and Edwardian silver pieces were marked at Birmingham.
Sheffield — crown (then rose). Opened in 1773 alongside Birmingham. The Sheffield mark was a crown on flatware and holloware until 1974, after which it changed to a rose. Sheffield is famous for silver cutlery and candlesticks.
Edinburgh — three-towered castle. The Scottish assay office since 1485. Edinburgh silver includes distinctive Scottish forms and is associated with many fine 18th and 19th century makers.
Glasgow — tree with fish and bell. Operated from 1819 to 1964. The elaborate Glasgow mark depicts the city's armorial bearings.
Dublin — crowned harp. The Irish assay office in operation since 1637. Irish silver, though often simpler in form than English, is highly collected, particularly Georgian pieces.
The date letter system
Every English assay office stamps a single letter on each piece to indicate the year it was assayed. The letters cycle through the alphabet — typically skipping J and usually Q, V, X, Y, and Z — before beginning a new cycle in a different typeface and with a different shield shape. A capital Gothic "A" is one year; a lowercase Roman "a" is another; a capital script "A" is another.
Reference charts for each assay office let you match a specific letter-and-typeface combination to a single year. Because each office cycles independently, the same letter can mean different years depending on the town mark it appears with. A London "D" might be 1779; a Birmingham "D" might be 1828. Always identify the town mark before looking up the date letter.
The duty mark — sovereign's head
From 1784 to 1890, the British government charged a tax, or "duty," on silver, and pieces assayed in that window carry an additional fifth mark — the head of the reigning sovereign — to show that the duty had been paid. George III's profile (1784-1820) gives way to George IV (1820-1830), then William IV (1830-1837), then a younger Queen Victoria (1837-1890). When the duty was repealed in 1890, the sovereign's head disappeared from hallmarks. A sovereign's head is therefore a useful quick indicator that a piece was assayed between 1784 and 1890.
The maker's mark
The fourth main mark is the maker's mark — typically a pair of initials inside a shield or cartouche. Registered maker's marks exist for most major assay offices going back centuries, so a clear mark can often be traced to a specific silversmith working in a specific shop during a specific range of years. Premier English makers like Paul de Lamerie (London, early 18th century), Hester Bateman (London, late 18th century), and Paul Storr (London, Regency era) are highly collected, and their marks can multiply a piece's value substantially.
Value implications
English hallmarks provide verified provenance that American silver rarely has. A clearly marked Georgian tea pot from a documented London maker of the 1780s can sell for $2,000 to $10,000 or more depending on form, size, condition, and maker. Regency and early Victorian hallmarked silver by recognized makers trades actively in the $500 to $5,000 range. Even modest hallmarked English flatware and holloware typically outperforms equivalent unmarked pieces because the marks supply the confidence buyers need. Before selling inherited English silver, identify and photograph every mark on every piece.
