1937 George VI Gold Proof Sovereign NGC PF66+ Cameo

1937 George VI Gold Proof Sovereign NGC PF66+ Cameo

The 1937 George VI Gold Proof Sovereign occupies a unique position in the history of British gold coinage.

Struck specifically to commemorate the Coronation of King George VI on 12 May 1937, the coin was issued exclusively as part of The Royal Mint’s special four-coin Gold Proof Coronation Set and was never produced as an ordinary circulating Sovereign. The Royal Mint records an issue of just 5,501 sets.

Its historical significance extends considerably further.

George VI became King unexpectedly following the abdication of his elder brother Edward VIII in December 1936, bringing an abrupt end to preparations for Edward’s new coinage.

Edward VIII’s intended Sovereign never entered normal production. Only a handful of Proof and pattern examples were created, with The Royal Mint stating that just six Edward VIII Sovereigns are thought to exist today.

George VI consequently inherited both the throne and a Royal Mint facing the urgent task of producing coinage for a new monarch.

The resulting 1937 Proof Sovereign became something remarkable: according to the Royal Mint Museum, the 1937 Sovereign family represents the only Sovereigns ever to bear the portrait of George VI.

This particular example has been independently authenticated and certified by Numismatic Guaranty Company (NGC) as PF66+ Cameo.

At the time of checking on 15 August 2026, the NGC Census supplied for this coin records just 3 examples in PF66+ Cameo, with only 8 examples graded higher.

It is an exceptional certified example of a Sovereign born directly from one of the most dramatic constitutional events in twentieth-century British history.

Why This Coin Stands Out

Few twentieth-century Sovereigns combine historical significance and numismatic scarcity as effectively as the 1937 George VI Proof Sovereign.

Its story begins not with George VI, but with his elder brother Edward VIII.

Edward became King following the death of George V in January 1936. The Royal Mint began preparing a new coinage bearing his portrait, including a Sovereign designed by Humphrey Paget.

But those coins would never enter circulation.

Edward VIII abdicated on 11 December 1936 amid the constitutional crisis surrounding his desire to marry Wallis Simpson. The abdication stopped the planned production of his coinage before its scheduled introduction.

His younger brother unexpectedly became King George VI.

The Royal Mint then commissioned Humphrey Paget to create the new King’s portrait urgently. According to the Royal Mint Museum, Paget completed George VI’s new coinage portrait in little more than a month.

For George VI’s Coronation, The Royal Mint produced a special four-coin Gold Proof set comprising:

• Five Sovereign Piece
• Double Sovereign
• Sovereign
• Half Sovereign

Only approximately 5,501 sets were produced.

This coin is the Sovereign from that historic Coronation issue.

Issued Within Just 5,501 Coronation Proof Sets

The 1937 Sovereign was not issued as a normal circulating Sovereign.

It was produced exclusively for the special four-coin Gold Proof sets created to commemorate the Coronation of George VI.

The Royal Mint records approximately:

5,501 sets

Each contained a Five Sovereign Piece, Double Sovereign, Sovereign and Half Sovereign.

This means the 1937 Sovereign was inherently limited from the moment it was produced.

Unlike many historic Sovereigns whose original mintages can run into hundreds of thousands or millions, the 1937 George VI issue was created specifically as a limited Proof issue for the Coronation.

The original issue should also be distinguished from the NGC population.

The 5,501 figure relates to the original Coronation Proof issue, while the NGC population of 3 relates specifically to examples currently certified at the PF66+ Cameo grade.

Our Coin Population vs Mintage guide explains why original issue figures and third-party grading populations should be treated as separate measurements.

Why NGC PF66+ Cameo Matters

This example has been independently authenticated, encapsulated and graded by Numismatic Guaranty Company (NGC) as:

PF66+ Cameo

The PF designation identifies the coin as a Proof.

The 66+ grade places the coin towards the upper end of NGC’s 70-point numerical grading scale, while the additional + designation indicates a coin approaching the quality required for the next numerical grade.

The Cameo designation recognises contrast between the frosted design elements and reflective Proof fields.

For a Proof Sovereign struck in 1937, the combination of a high numerical grade and Cameo designation is particularly notable.

For more on Proof grading terminology and the differences between the major grading services, see our PCGS vs NGC guide.

NGC Population

At the time of checking on 15 August 2026:

NGC PF66+ Cameo: 3

Higher: 8

The NGC Census supplied for this coin therefore records only three examples at this exact PF66+ Cameo grade.

Unlike the PF70 modern coins we have listed elsewhere, this coin should not be described as Top Pop because NGC records eight examples at higher grades.

Its scarcity statement should instead remain precise:

NGC PF66+ Cameo Population 3 | Only 8 Higher

The original issue and NGC population again measure different things. The approximately 5,501 Coronation sets establish the scale of the original issue, while the NGC Census shows how few examples have currently achieved this particular combination of grade and Cameo designation.

Population figures can change as additional coins are submitted for certification, which is why Sterling Bullion Partners records the date on which each population figure is checked.

Our Coin Population Report guide explains how NGC and PCGS population data works and how certified population should be interpreted.

Born from the Abdication Crisis

The historical circumstances behind the 1937 Sovereign are extraordinary.

Edward VIII succeeded George V in January 1936, and The Royal Mint began preparing the coinage of the new King.

Humphrey Paget created Edward’s intended coinage portrait.

But Edward VIII’s reign lasted less than a year.

His determination to marry the American divorcée Wallis Simpson triggered a constitutional crisis. On 11 December 1936, Edward announced that he was relinquishing the throne.

The planned Edward VIII coinage was consequently abandoned before entering normal circulation.

The Royal Mint Museum confirms that although trial and pattern pieces were produced, no coins bearing Edward VIII’s portrait ever entered circulation.

His younger brother Albert subsequently became King George VI.

That sudden transition directly led to the creation of the coin offered here.

Edward VIII – The Coinage That Never Was

The Sovereign provides a particularly striking connection between the two brothers.

Before Edward’s abdication, The Royal Mint had already produced a tiny number of experimental and Proof coins bearing his portrait.

The 1937 Edward VIII Sovereign is now one of the rarest British coins in existence.

The Royal Mint states that just:

6 examples are thought to exist

and in 2020 it brokered the sale of one example for £1 million.

These were not normal production Sovereigns. They were Proof and pattern pieces created in preparation for a coinage that never entered circulation.

The Royal Mint itself describes Edward VIII’s issues as the:

“coinage that never was.”

The 1937 George VI Sovereign therefore represents the coinage that ultimately emerged from that extraordinary episode in British royal history.

The Only Sovereign to Bear George VI’s Portrait

Perhaps the most important numismatic characteristic of the 1937 Sovereign is that George VI’s portrait would never appear on another Sovereign issue.

The Royal Mint Museum confirms that the 1937 coins are:

the only Sovereigns to bear the portrait of George VI.

Although Sovereigns were struck again during George VI’s reign in 1949, 1951 and 1952, they were produced for emergency purposes.

Those later coins deliberately carried the portrait of George V
