The anchor is one of the most important symbols in the world of silver hallmarks, but its meaning depends entirely on context. On British silver, the anchor identifies the Birmingham Assay Office. On other silver, an anchor may be part of a maker's mark, a national purity symbol, or a decorative element with no official significance. Understanding the difference is critical for accurate identification.
The Birmingham Anchor: Britain's Busiest Assay Office
The anchor's primary meaning in silver hallmarking is as the town mark for Birmingham, England. The Birmingham Assay Office was established in 1773 by an Act of Parliament (alongside Sheffield). The anchor symbol was adopted — legend says because the enabling legislation was debated at the Crown & Anchor pub in London's Strand district.
When you see an anchor as part of a complete British hallmark set (typically alongside a lion passant, a date letter, and a maker's mark), you can be confident the piece was tested and verified at Birmingham. Today, the Birmingham Assay Office tests more items annually than any other assay office in the world — over 6 million articles per year.
Other Anchor Marks on Silver
Not every anchor on silver means Birmingham. Here are other contexts where anchors appear:
Gorham Manufacturing Company (USA)
Gorham, one of America's most prestigious silvermakers, used an anchor as their trademark from 1831 onward. The Gorham anchor is typically accompanied by a lion and a capital "G." Gorham silver is American-made and has no connection to Birmingham. Their pieces are marked with "STERLING" (not a lion passant) to indicate purity.
Genoese Silver (Italy)
Genoa, the great Italian maritime republic, used an anchor in its silver marking system. Genoese silver from the 17th through 19th centuries may carry an anchor alongside Italian purity marks. The style and context differ significantly from the Birmingham anchor.
Russian Silver
Some Russian silver from the Imperial period features anchor marks, particularly pieces connected to naval or maritime contexts. These are typically maker's marks rather than assay marks.
Decorative Anchors
Some silvermakers, particularly those crafting nautical-themed pieces, incorporate anchors as decorative elements or maker's marks. These should not be confused with assay office marks.
How to Tell if an Anchor Mark Means Birmingham
A genuine Birmingham assay mark has these characteristics:
- It appears as part of a complete hallmark set — alongside a lion passant (sterling mark), a date letter, and a maker's mark
- The anchor is plain — no rope, crown, or other embellishments. Just a simple anchor shape
- It is individually struck — showing slight depth and crisp edges from a steel punch
- It sits in a shaped cartouche — the outline around the anchor changes slightly over different periods
If you see an anchor alone, without accompanying British hallmarks, it is almost certainly not a Birmingham mark. It may be a maker's mark, a foreign mark, or a decorative element.

What to Look For When Buying
When examining a piece of silver with an anchor mark:
- Check if other hallmarks are present — a lone anchor is not a British hallmark
- Verify the lion passant appears alongside the anchor for English sterling
- Note the date letter and look it up in Birmingham's specific date chart
- Research the maker's mark — the Silver Marks app identifies over 15,000 marks instantly
- Examine the anchor's form — the Birmingham anchor is plain without embellishments
