Struck in solid 22 carat gold, the coins feature a passage from one of Her Majesty’s first official speeches.

This is such a rare limited edition that a Holo-Proof security feature has been introduced to prevent copying. Each coin features a different silhouette set behind the words ‘I solemnly promise so to do’.  Tilt the coin on an angle and this portrait fades from view, like a holographic image.  The half sovereign features a silhouette of the portrait of Her Majesty that appeared on the British 1977 Silver Jubilee coinage.  The sovereign features a silhouette of the portrait that appeared on the British 1993 Ruby Jubilee coinage.
