How to Read a Hallmark in Four Steps

A hallmark is one of the oldest forms of consumer protection still in use. In Britain it dates back to the fourteenth century, and the system has survived largely intact.

The marks are tiny, usually in a row, and typically found on the back of a spoon, the underside of a bowl, the rim of a tray or the bottom of a piece of hollowware. A loupe or a phone camera on macro helps enormously.

There are four things to find, and they come in a conventional order.

Step 1: the standard mark, which tells you the metal

This confirms the purity of the metal and is the whole point of the system.

In the British tradition, sterling silver is marked with a walking lion — the lion passant — for England. Scotland and Ireland have used their own standard marks. Higher-purity Britannia silver has its own figure. Gold and platinum have their own marks and numerical fineness figures.

If there is no standard mark at all, you are probably not looking at hallmarked precious metal, whatever else is stamped on it.

Step 2: the town mark, which tells you where it was tested

Each assay office had its own symbol. London used a leopard’s head, Birmingham an anchor, Sheffield a crown and later a rose, Edinburgh a castle, Dublin a harp, and so on. Several offices have closed over the centuries, which is itself useful dating information.

The town mark is the one that most often narrows a piece down quickly, because an office that closed in a particular year gives you a hard latest-possible date.

Step 3: the date letter, which gives the year

This is the mark that does the real work. Each assay office ran cycles of letters, changing annually, with the typeface and the shape of the surrounding shield changing between cycles.

That means a date letter is only meaningful in combination with the town mark and the shield shape. The letter A from London is not the same year as the letter A from Birmingham, and London has used the letter A many times.

Published tables for each office are widely available, including from the assay offices themselves, and reading one takes a minute once you know which office you are in.

Step 4: the maker’s mark, which tells you who made it

Usually initials in a distinctive surround. Registers of makers’ marks have been kept by the assay offices for centuries, and many are searchable.

This is the mark that most affects value, because a well-regarded maker can multiply a price substantially.

Two more marks you may see

A monarch’s head indicates duty paid, and appears on British silver for the period when a duty was in force. Its presence or absence is a useful cross-check on the date letter.

Commemorative marks were issued for particular royal occasions and, when present, date a piece to within a year or two immediately.

What fakes and misunderstandings look like

EPNS is not silver. It stands for electroplated nickel silver: a base metal with a thin silver coating. It is stamped with letters rather than with the pictorial hallmark series, and that difference is the quickest test there is.

Sterling or 925 alone is not a British hallmark. Those marks are common on imported and modern silver and may be entirely honest, but they are not the assay system and they carry no independent verification.

Struck-in marks from another object. A genuine but crude fraud involves cutting the hallmarked section from a damaged piece and soldering it into another. Look for a faint outline around the marks, a difference in colour or surface, or marks that sit oddly in relation to the shape.

Marks that are too crisp. Hallmarks on a piece that has been used for two centuries should show wear consistent with the rest of the object. Sharp marks on a worn spoon deserve a second look.

The habit worth building

Turn things over. Most people never do, and the marks are on almost everything: cutlery, picture frames, sugar tongs, napkin rings, christening mugs.

It takes about thirty seconds, and it is the difference between an old spoon and a spoon made in Sheffield in a specific year by a named workshop.
