The town mark

The Sheffield Assay Office strikes a distinctive symbol — Tudor rose (since 1975 for both gold and silver; previously a crown for gold). This town mark identifies where a piece was assayed, so spotting it on a ring, chain, or piece of silverware tells you which office tested and guaranteed its metal content.
