William Wyon was a prolific nineteenth-century engraver, well-loved for his finely-wrought, neoclassical designs. He was employed by the Royal Mint from 1816 as Second Engraver before becoming Chief Engraver in 1828. During his long career he executed dies for many notable coins, including the 'Young Head' effigy of Queen Victoria as well as the much sought after but very scarce 'Una and the Lion' five pound and the unused 'Three Graces' pattern.
