A 22 carat gold 2018 proof Sovereign with a crown privy mark in its original presentation box from The Royal Mint.

Two Centuries of Sovereigns

The first Sovereigns were struck during the reign of Tudor king Henry VIII. Centuries later, a new gold coin bearing this name was introduced, following a major overhaul of British coinage. This Sovereign, first minted in 1817, established specifications that are still strictly followed today.

All Sovereigns weight exactly 7.98 grams and are composed of 22 carat gold. That’s a gold weight of 7.32 grams or .2354 troy ounces. Sovereigns measure 22.05 millimetres in diameter and have a nominal face value of one pound sterling though their gold content means they command significantly higher prices.

Sovereigns once circulated across the globe but production ceased with the outbreak of the First World War. Reintroduced in 1957, annual issues attract investors and collectors with limited edition proof Sovereigns - hand-finished for a flawless effect - the most sought-after.

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 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.

Just 13,350 of these 2018 proof Sovereigns were issued, including those in sets.

A Limited Edition Collectible

Your 2018 proof Sovereign comes in its original packaging from The Royal Mint. This consists of an attractive, high-shine wood presentation box in which the coin is situated inside a capsule. Also included: a numbered certificate of authenticity, confirming the specifications of this collector’s piece.

If you’re in the market for a 2018 Sovereign there are a few alternative options to consider:

  • Our bullion 2018 Sovereigns don’t feature the privy mark but contain the same amount of gold as the proof Sovereign
  • Our 2018 bullion Half Sovereigns are half the weight of ‘full’ Sovereigns, great if you want to collect the date for a smaller price
  • Another option: our best value, mixed year Sovereigns, great if you’re just looking to buy gold coins

All Sovereigns, including those issued in 2018, are exempt from Capital Gains Tax as UK legal tender and free from VAT in the UK and EU as investment grade gold.
