Royal Wedding anniversary celebrated by Ascension Island in huge style with a 70-ounce coin

An incredible feat for any couple but a staggeringly rare one for a sitting monarch, a platinum wedding anniversary marks seven decades of commitment. Queen Elizabeth II is one of the worlds longest-ever serving monarchs, and probably one of the most admired. Her marriage to Prince Philip has been in the spotlight for all that time and many previous anniversaries have had numismatic celebrations, so this one was never going to be overlooked.

Many of the major Commonwealth mints are issuing coins, but none will be as unique as the Pobjoy Mint’s new effort. Already available as a one-ounce sterling silver coin, this design has overdosed on growth hormone and expanded to over two-kilograms in weight. It’s picked up some gilding and diamonds along the way as well. Now seventy-ounces of fine 0.999 silver in weight, the reverse face has several elements highlighted in gold plating, mainly the accoutrements of power that come with the office of state. Elizabeth’s crown and Philips neck-ware have been encrusted with 70 diamonds with a combined weight of 1-Carat.

The obverse is an unusual one, featuring a double effigy of the pair, much like the new Royal Mint design, although we think the latter one superior. Packaging looks to be of the best quality. At 130 mm in diameter, a coin this large needs something a bit special and the wooden chest seems well up to the job. Price is a staggering £13,600 ($19,500 USD). Between the niche subject matter, ambitious spec and handmade production method, we expected a hefty cost, but not that high. The mint is claiming half the 70-coin mintage has already gone on launch day, so clearly a market exists.

Available to order now, you can contact Pobjoy at to enquire about purchasing and availability.



Achieving a Platinum wedding anniversary is an incredible feat and, in order to celebrate the Royal Couple’s milestone, Pobjoy Mint has produced one of our largest coins to date.

With a weight of 70oz, this coin would make a beautiful centrepiece to any numismatic collection. Production is technically very demanding and each piece has been encrusted with 70 Diamonds (Total Weight of 1 Carat). Spot gold plating has been used to highlight certain pieces of jewellery. Each coin is hand finished in-house by our master craftsman and many hours are spent finishing each coin due to the fine attention to detail.

Pobjoy Mint has received exclusive approval from HM Queen Elizabeth to feature a dual-effigy of herself and HRH Prince Philip together. We are incredibly excited to have this permission as it is the first time that this portrait has ever been used on a coin! This issue limit of this coin is just 70 pieces and each one will be accompanied with a matching numbered certificate to prove its authenticity.

The State Opening of Parliament is a formal occasion which marks the beginning of a parliamentary session or after a general election. It is an elaborate ceremony which showcases British History, culture and politics during which The Queen wears the Parliament Robe of State and the Imperial State crown with all accompanying regalia. For over 500 years the Opening of Parliament has symbolised the unity of the Sovereign, the House of Lords & the House of Commons.

HM Queen Elizabeth II and HRH Prince Philip have had an astonishing life together and have dedicated their lives to the duty of monarchy.  The couple first met at the Royal Naval College in Dartmouth in 1939 when the Queen was just 13- years-old, and began exchanging letters before eventually becoming formally engaged in 1947, following the Queen’s 21st birthday. The royal pair married later in the same year and in November this year will celebrate their Platinum Wedding Anniversary. The Monarch was crowned just five years after their wedding following the death of her father King George VI, who died aged only 56, and although the transition changed their lives forever the couple have always approached their royal duties with a sense of humour and affection for each other that, over the decades, is testament to their enduring love.
