Inverness is not an Assay office but is one of the Scottish Provincial towns at which silversmiths worked. The records are incomplete but there was a minute book of the Hammermen's craft (which included silversmiths), dated between 1690 and 1861. Unfortunately only a small part of the proceedings are recorded in it (Jacksons). There are several punches that were used to denote Inverness work. These include a camel, a cornucopia and the letters "INV" or "INVSS". Other marks include a mask and an 8-pointed star.
Sugar tongs from Inverness are rare.
