Unlock our date letter archive. Just £2 for lifetime access.
The date letter was a compulsory hallmark in Britain until 1999. This small letter records exactly when the piece it is marked upon was tested and certified.

Date letters were unique to each UK Assay Office until 1975, when they all began to use the same font and cycle.
Our archive holds a copy of every date letter mark applied by Birmingham Assay Office since we opened in 1773.
