What Are Silver Hallmarks?

Silver hallmarks are small stamped symbols on silver objects that guarantee the metal's purity. Introduced in 1300 at Goldsmiths' Hall in London, hallmarking is one of the oldest forms of consumer protection in the world. A complete hallmark typically includes four elements: a standard mark (purity), a town mark (assay office), a date letter (year of assay), and a maker's mark (manufacturer's initials).

Understanding these marks allows collectors, dealers, and enthusiasts to determine where, when, and by whom a piece of silver was made, which directly affects its value and authenticity.

Did you know? The word "hallmark" comes from Goldsmiths' Hall in London, where items were taken to be assayed and marked beginning in the 14th century. Today, the term is used worldwide to describe any mark of quality or authenticity.

Frequently Asked Questions

What do the symbols on the bottom of my silver mean?

The symbols stamped on silver are called hallmarks. They typically indicate the silver purity (e.g., lion passant for British sterling), the assay office where it was tested, a date letter showing the year, and the maker's initials. Together, these marks tell you exactly what your silver is and where it came from.

How can I tell if my silver is real or plated?

Real sterling silver will have hallmarks such as "925", "Sterling", or a lion passant stamp. Silver-plated items are marked "EPNS" (Electroplated Nickel Silver), "A1", or "Silver Plate". If you see no marks at all, the piece may be unmarked coin silver or a reproduction. A magnet test can help too, as real silver is not magnetic.

What does "925" mean on silver?

The number "925" means the item is 92.5% pure silver, which is the international standard for sterling silver. The remaining 7.5% is usually copper, added for durability. This stamp is used worldwide and is the most common silver purity mark you will encounter.

How do I read date letters on British silver?

British assay offices use a rotating alphabet system where each letter represents a specific year. The letter style (font), case (uppercase or lowercase), and shield shape all vary by cycle and assay office. For example, London used a Gothic lowercase "a" for 1876 and a Roman capital "A" for 1896. Our UK Hallmarks page has complete date letter tables.

Are European silver marks different from British ones?

Yes. Each European country has its own hallmarking system. France uses an eagle head for 18-carat gold and an owl for imported silver. Germany uses a crescent and crown symbol for 800-grade silver. Russia historically used the kokoshnik mark. Our European Hallmarks guide covers the major systems in detail.
