As Her Majesty The Queen and His Royal Highness The Prince Philip, Duke of Edinburgh celebrate their platinum wedding anniversary, The Royal Mint and Royal Mail have come together to mark the longest marriage in royal British history.

Few people achieve such a landmark anniversary and the world has watched the royal couple’s journey, from young newly-weds in post-war Britain to great-grandparents in the digital age.

This limited edition coin and stamp set contains six photographic stamps charting the young couple during the year of their wedding in 1947, from the moment news broke of their engagement to the honeymooning newly-weds on holiday. A specially designed and dated handstamp features a contemporary silhouette portrait, marking the date of the platinum wedding anniversary.

Just 50 covers are available containing the commemorative £5 coin struck in 22 carat gold and finished to Proof standard. The coin’s obverse features a special combined portrait of the couple created by sculptor Etienne Millner, which is paired with a reverse design by John Bergdahl, inspired by both The Queen and The Duke of Edinburgh’s love of horses.
