British Hallmarks by City: Complete Guide
British hallmarks are legally required stamps that verify the purity of precious metals like gold, silver, and platinum. These marks are applied by official assay offices across the UK and have been in use for centuries. Each hallmark typically includes a series of symbols indicating:
-
The standard of metal purity (e.g. 18K gold or sterling silver)
-
The city where the item was assayed
-
The maker's mark
-
A date letter (for many pieces before 1999)
-
Additional symbols like duty marks or commemorative stamps
Understanding the city hallmark is essential to identifying where and when a piece was evaluated and marked.
