An Apothecaries Weight

During a guided walk on the Tower of London foreshore last week, a tiny artefact (1cm square) was found eroding out of one of the stratified deposits at the eastern end of the site, near Tower Bridge.

After consultation with the Portable Antiquities Scheme and some research at TDP Towers, it has been identified as an apothecaries weight, most likely made of copper alloy. The stamp indicates it is an approved weight and has been identified as a Sheffield mark, dating to 1826.
