Leopard's Head Symbol on Silver or Gold
The leopard's head is the town mark of the London Assay Office and the oldest British hallmark, in continuous use since 1300. Until 1821 the leopard wore a crown; the uncrowned head marks pieces after that date, which makes the crown a quick dating clue.
In medieval heraldry a 'leopard' meant a lion shown face-on, so the mark is actually a frontal lion's face. It appears with the fineness mark, date letter, and maker's mark on items assayed at Goldsmiths' Hall in London.
