Weighing 3.61 kilograms of pure gold and set with 6,462 natural diamonds, the one-off masterpiece is the size of a dinner plate. Commissioned to mark Queen Elizabeth II’s Platinum Jubilee, the extraordinary piece took more than 83 artisans across eight countries to complete.
Though officially issued by the British Overseas Territory of Saint Helena as a £10,000 coin, it carries far greater value. In 2022, the coin was independently appraised at £16 million, yet it will enter the market with a surprisingly modest auction estimate of £2–3 million.
The coin’s international creation mirrors the Queen’s global legacy. Diamonds were sourced and polished in Australia, South Africa, and Canada, certified by the Gemological Institute of America. The design originated in Britain, refined in Sri Lanka and England, engraved in Singapore, and minted in Germany and the Netherlands, before final assembly in India.
Measuring 235mm in diameter and 30mm thick, the coin incorporates 11 smaller embedded coins. Five bear effigies of Elizabeth II, while others depict regal motifs including the tiaras she wore and the six virtues—Truth, Justice, Charity, Courage, Victory and Constancy—drawn from the Queen Victoria Memorial.
Adding a modern twist, the auction house will accept cryptocurrency bids.
The auction, titled The Crown Coin: Her Masterpiece, will take place on September 25 at Stanley Gibbons Baldwin’s London flagship, with global participation available online.
