Queen Elizabeth and Prince Philip will host a private party to celebrate their 70th wedding anniversary.

The couple, who wed on Nov. 20, 1947, will celebrate their platinum wedding anniversary with a dinner party at Windsor Castle, where only the pair's closest family and friends will be in attendance, Daily Mail reports.

While this will be the first time any members of the royal family have reached this milestone, there will be no festivities for the public to commemorate the occasion. This is in contrast to their silver, golden and diamond anniversaries, which included national services of thanksgiving at Westminster Abbey and the release of official photographs.

For the couple's golden anniversary, the Queen spoke highly of her husband and the "remarkable 50 years" they have shared together.

"He is someone who doesn't take easily to compliments but he has, quite simply, been my strength and stay all these years, and I, and his whole family, and this and many other countries, owe him a debt greater than he would ever claim, or we shall ever know," she said.

However, despite the lack of a public celebration, the Royal Mint will be releasing a full set of commemorative coins.

A collection of limited-edition coins will be offered in a variety of styles to mark the royal couple's anniversary.

One coin will read "70 years of marriage" below an image of the couple's royal crest and crown.

The Royal Consort joins Her Majesty on both sides of another coin, which features the pair side-by-side on horseback. The image reflects the couple's mutual love of horses.

The most detailed coin will be tri-coloured to commemorate Queen Elizabeth and Prince Philip's monumental anniversaries. It depicts a side profile of the couple on one side and various flowers on the other, each holding significant meaning.

The silver outer circle represents the pair's 25th anniversary and shows irises, symbolizing promise, faith and wisdom. The ivy depicts wedded love, fidelity and affection, while myrtle serves as the Hebrew emblem of marriage.

The gold middle circle celebrates Queen Elizabeth and Prince Philip's 50th anniversary by showcasing roses to represent inner joy, happiness and true love. The sweet pea and honeysuckle are the flowers which represent each birth month of the twosome.

The platinum plated inner circle, representing the couple's 70th anniversary, contains an orchid, which defines long life and love.

"They have built an enduring partnership that is an inspiration to us all, as Britain celebrates this unique personal moment in royal history," a spokesman for the Royal Mint said.

The set includes a gold proof, fine silver, silver proof and brilliant uncirculated coins, varying anywhere from £5 ($6.58) to £20 ($26.32).
