Queen Elizabeth has reached several milestones over her tenure as the ruling monarch. In 2015, she became the longest-reigning monarch in British history. She’s also the longest-reigning female monarch across the globe and is the oldest monarch to ever rule over England.

Yes, the years have been kind to Elizabeth as a ruler, but as it turns out they’ve been kind to her personally as well, because on Sunday, Nov. 20, the Queen and her husband Prince Philip will celebrate their 70th wedding anniversary.

While this would certainly be enough reason for Elizabeth and Philip to shout from the rooftops, it appears the duo is instead opting to have a quite dinner celebration at home in Windsor Castle to celebrate their platinum anniversary.

According to the Daily Mail, only the couple’s closest friends and family are invited to attend the soiree. This marks a departure from tradition for the pair, who had national celebrations for their silver, gold, and diamond anniversaries.

However, as a source told the Daily Mail, “They feel they can’t top the golden and diamond wedding anniversaries and don’t particularly want to.”

Though the 70-year mark is an enormous figure, the Queen and Prince Phillip actually have a few more years to go before they are officially the longest married royal couple. As of now that title belongs to Japan’s Prince Mikasa and Princess Yuriko. They were married for 75 years before Mikasa’s death at the ripe old age of 100 in 2016.

But, just because the Queen and her Prince don’t want to celebrate in public doesn’t mean their adoring fans can’t get in on the action. As Town & Country reported, there will be plenty of commemorative souvenirs to go around for the event including an uncirculated £5 coin that features both Prince Philip's and the Queen's profiles.

That coin and another £20 commemorative coin are both edged with "wedded love has joined them in happiness 1947-2017," making it the perfect keepsake to remember that love truly is forever. (At least for some royals.)
