When you buy a Kingsby Bar, you are purchasing a bar that has been hallmarked and independently verified by The Goldsmiths’ Company, an institution that was asked in 1478 to supervise Britain’s first marking system to guarantee the fineness of precious metal. Each Kingsby bar is rigorously checked and marked for fineness and quality. The Goldsmiths’ Company Assay Office is a government regulated institution which gained its Royal Charter in 1327 soon after King Edward I passed a statute requiring that gold and silver of a defined standard be marked with a Leopard’s head. This mark later became known as the King’s mark – every Kingsby Bar carries this prominent mark.
