The Chester Mark - Re-registered at Sheffield Assay Office

The Chester Mark - Re-registered at Sheffield Assay Office

Last year, we announced that award winning designer Lucy Quartermaine had chosen to work with us here at Sheffield Assay Office.

We were also delighted to re-introduce the Chester Town Mark which had become dormant since Chester Assay Office closed it’s doors in 1962.  Lucy has been using this mark as her company is based in Chester.

Following this announcement, we had a number of companies who expressed an interest in using the mark and we therefore felt it prudent to register it as a trademark to protect it’s use.  In this way it is possible to monitor and control it’s usage and ensure it is only struck on products where appropriate.  The mark is used as an additional mark and not to be confused with the mandatory UK hallmarks.

This has now been confirmed by the Trade Marks Registry.  If any company with a Chester connection is interested in using the mark then please don't hesitate to contact us. 


The Sheffield Assay Office was established in 1773, under an Act of Parliament and today the company assays and hallmarks the precious metals - silver, gold, platinum and palladium. Sheffield Assay Office is one of only four UK assay offices who all work to uphold the Hallmarking Act of 1973 and continue to ensure consumer protection for customers purchasing precious metals.
