Buy a 2018 Elizabeth II Piedfort Gold Proof Sovereign Sapphire Jubilee Coin

(VAT Exempt)
Just 1,930 issued! This scarce proof Sovereign was struck in the year of Her Majesty, Queen Elizabeth II’s sapphire jubilee. That’s the anniversary celebrated for 65 years of marriage or - in this case - 65 years on the throne. To mark the occasion The Royal Mint authorised the addition of a special privy mark on the reverse of coins in the gold proof Sovereign family. This appears just next to the date, below the classic Saint George and the dragon engraving. This was designed for the first gold Sovereigns by Italian artist Benedetto Pistrucci. Its paired with Jody Clark’s portrait of Her Majesty Queen Elizabeth II, introduced to British money in 2015. As well as the variant reverse design there’s something else that’s unusual about this proof Sovereign: it’s twice the weigh of a regular ‘full’ Sovereign and twice the thickness. Piedfort proof Sovereigns are rare and there were only 1,930 issued in 2018. This highly collectible coin is composed of 15.96 grams of 22 carat gold and maintains the diameter of a normal Sovereign: 22.05 millimetres. It’s offered in its original presentation case from The Royal Mint with a numbered certificate of authenticity.

Gold proof piedfort Sovereign struck in 2018 with a special privy mark to celebrate the Queen's sapphire jubilee.

Piedfort Proof Sovereigns

This is a rare example of a piedfort Sovereign: twice the weight of an ordinary 'full' Sovereign at 15.96 grams of 22 carat gold, retaining the same diameter of 22.05 millimetres.

The Royal Mint has been offering double-weight, double-thickness editions of their commemorative coins since 1982 but they're part of a much older tradition, dating back to medieval times. These coins were particularly associated with France where 'piedfort' means 'heavy measure'.

Spink only lists three modern piedfort Sovereigns, issued by The Royal Mint in 2017, 2018 and 2019. This is your chance to get hold of the first.

This gold proof piedfort Sovereign is one of only 1,930 offered by The Royal Mint in 2018.

Sapphire Anniversary Privy Mark

For much of its long history the modern Sovereign has featured an iconic reverse design, crafted by Italian artist Benedetto Pistrucci. His instantly-recognisable Saint George design shows England's patron saint mounted on a horse, slaying a dragon which cowers underfoot.

For this year only, the reverse of coins in the Sovereign family also features a tiny crown privy mark to the left of the date. This was authorised by The Royal Mint to mark Her Majesty the Queen's Sapphire Jubilee: a celebration of 65 years since her coronation.

Pistrucci's reverse is paired with Jody Clark's portrait of Elizabeth II. Introduced in 2015, this is the fifth official effigy used on the Queen's coinage since her coronation in 1953. Clark's initials – JC – appear below the truncation of her neck.
