Platinum coins mark the Queen and Philip's 70th wedding anniversary

The Queen and the Duke of Edinburgh appear on the coins, specially struck as they become the first British royal couple to celebrate a platinum wedding anniversary.

They married at Westminster Abbey in front of 2,000 guests on November 20 1947.

The service was broadcast live to 200 million radio listeners and was a welcome celebration as Britain faced post-war austerity.

The Royal Mint said they appear in a double profile portrait on one side of the coin, while the reverse has them on horseback and is edged with the words "wedded love has joined them in happiness 1947-2017".

A spokesman said: "They have built an enduring partnership that is an inspiration to us all, as Britain celebrates this unique personal moment in royal history."

The combined portrait was designed by sculptor Etienne Milner to represent a sense of duty, with Philip supporting the Queen in his role of royal consort.

The horseback image was created by artist John Bergdahl to reflect the couple's passion for all things equestrian.

The Royal Mint said the collection which includes a gold proof, fine silver, silver proof and a brilliant uncirculated coin ranges in price from £5 to £20.
