2025 Date Letter

 

Introducing the 2025 date letter

The date letter for 2025 is a lowercase “a”, marking the final character in the current font cycle. A new cycle will begin on January 1st, 2026, with the letter “B” introduced in a refreshed font, case, and shield shape.

While the date letter is a non-compulsory part of the hallmark, it changes annually across all UK Assay Offices on the 1st of January. Once the full alphabet has been used, a new style is introduced, ensuring that each date letter is visually unique and corresponds to one specific year only.

This system provides an easy way to identify and date hallmarked items — a valuable detail for jewellers, collectors, and anyone interested in the provenance of precious metals.
