World's most valuable coin made in honour of the late Queen will go on auction this month

One of the most significant moments in numismatic history is set to take place this month as the world's most valuable coin will be auctioned. The Crown Coin: Her Masterpiece was conceived as a tribute to Queen Elizabeth II's 70 years of service and features five official effigies of Her Majesty alongside personifications of the six virtues represented on the Victoria Memorial.

The incredible coin was last independently valued at £16 million in 2022. Now, it comes to market with a starting auction estimate of between £2million and £3million, though experts suggest its rarity and cultural significance could see it achieve far more when it goes under the hammer at Stanley Gibbons Baldwin's. A once-in-a-lifetime opportunity to acquire the coin, which involved a collaboration of 83 artisans across eight countries, will take place on September 25.

The magnificent artefact measures 235mm in diameter, contains 3.61 kilograms of gold, and is adorned with an extraordinary 6,426 GIA-certified diamonds, weighing 483.57 carats in total.

With a £0 starting bid, the auction will take place later this month at Stanley Gibbons Baldwin's headquarters on the Strand in London, with global bidding available online.

In an unprecedented move for an asset of this stature, cryptocurrency will also be accepted, subject to verification.

The Crown Coin: Her Masterpiece was minted by The East India Company. The diamonds were cut and polished in Australia, South Africa, and Canada, then certified by the Gemological Institute of America (GIA).

The coin's design was conceived in Britain, refined in Sri Lanka and England, engraved in Singapore, coins minted in Germany and the Netherlands, and finally assembled in India, echoing the global reach of Her Majesty's influence.

"This is more than a coin; it is a cultural artefact," said a spokesperson from Stanley Gibbons Baldwin's.

"The Crown Coin: Her Masterpiece stands alongside the most celebrated creations in numismatic history, from the legendary 1,000 Tola Gold Mohur of Mughal Emperor Jahangir to the great commemorative works of European royalty. It is a once-in-history tribute to a sovereign whose reign will never be equalled."
