Description
2017 Britannia 30th Anniversary 1oz Gold Proof NGC PF70 Ultra Cameo
The 2017 Britannia 1oz Gold Proof was created to celebrate the 30th anniversary of the Gold Britannia, first introduced by The Royal Mint in 1987.
For this anniversary year, The Royal Mint commissioned a new interpretation of Britannia from Louis Tamlyn, then a fine art student at Central Saint Martins.
Rather than simply reproducing the familiar standing Britannia associated with the bullion coin, Tamlyn created a distinctly contemporary interpretation for the 2017 Proof collection.
The design incorporates a special:
30th Anniversary Trident Mark
containing the number:
30
to commemorate three decades of the Gold Britannia.
The coin is struck in 999.9 fine gold, weighs 31.210g, measures 32.69mm in diameter and carries a denomination of £100.
This particular example has subsequently been independently authenticated and certified by Numismatic Guaranty Company (NGC) as:
PF70 ULTRA CAMEO
At the time of checking on 30 August 2026, the NGC certification evidence supplied for this exact issue records:
NGC PF70 Ultra Cameo Population: 15

Why This Coin Stands Out
- Celebrates the 30th Anniversary of the Gold Britannia
- Special Louis Tamlyn Britannia design
- Distinctive 30th Anniversary trident mark
- Official Maximum Coin Mintage: 280
- Reported actual mintage: 264
- 1 troy ounce of 999.9 fine gold
- Struck to Proof quality
- Official £100 UK denomination
- Queen Elizabeth II obverse by Jody Clark
- Certified NGC PF70 Ultra Cameo
- Highest numerical Proof grade
- NGC PF70 Ultra Cameo population of just 15

The combination of the anniversary-specific Louis Tamlyn design, extremely small original issue and NGC PF70 Ultra Cameo population of just 15 gives this particular example several distinct areas of collector interest.

⸻
Maximum Coin Mintage of Just 280
The official Royal Mint specification records a:
Maximum Coin Mintage: 280
for the 2017 £100 1oz Gold Proof Britannia.
Specialist numismatic records subsequently report an actual mintage of:
264 coins.
For accuracy, these figures should be understood separately:
Royal Mint Maximum Coin Mintage: 280
Reported Actual Mintage: 264
NGC PF70 Ultra Cameo Population: 15
The first represents the maximum number authorised within the Royal Mint’s mintage structure.
The second is the reported number actually produced.
The third records the number displayed by NGC at PF70 Ultra Cameo at the time of checking.
NGC population figures can change as further coins are submitted and certified, which is why the population is dated.

Celebrating 30 Years of the Gold Britannia
The Gold Britannia was introduced by The Royal Mint in 1987.
Thirty years later, the 2017 collection marked this milestone with special anniversary details and a new artistic interpretation of Britannia.
The Royal Mint describes Britannia as an evolving national icon whose appearance has changed throughout British history.
For the 2017 Proof collection, The Royal Mint selected Louis Tamlyn, then studying at Central Saint Martins, to create a contemporary interpretation reflecting a modern Britain while retaining the historic identity of Britannia.
This makes the 2017 Proof significantly different visually from the standard Britannia bullion coin produced during the same year.
⸻
Louis Tamlyn’s Contemporary Britannia
The reverse was designed by Louis Tamlyn.
Tamlyn’s interpretation presents Britannia as a modern embodiment of Britain while retaining the traditional attributes associated with the national figure.
The Royal Mint describes the design as representing a forward-thinking nation rooted in rich history.
The design also incorporates:
radial lines
and the special:
30th Anniversary trident mark
creating a composition specific to the anniversary Proof collection.
This is an important distinction from the 2017 bullion Britannia.
The bullion issue uses Philip Nathan’s classic standing Britannia, whereas this Gold Proof features Louis Tamlyn’s separate contemporary design.
⸻
The 30th Anniversary Trident Mark
One of the defining characteristics of the 2017 Proof Britannia is its celebratory anniversary mark.
The design incorporates a:
trident
containing:
30
to commemorate the 30 years since the introduction of the Gold Britannia in 1987.
The mark forms part of the anniversary-specific reverse and immediately identifies the coin with the Gold Britannia’s 30th anniversary.
Combined with Louis Tamlyn’s one-year design, it gives the 2017 Proof a distinctive identity within the wider Britannia series.
⸻
Queen Elizabeth II Obverse
The obverse features the fifth definitive coinage portrait of:
Her Late Majesty Queen Elizabeth II
designed by:
Jody Clark.
The Royal Mint confirms Jody Clark as the obverse designer for the 2017 Gold Proof Britannia.
The surrounding inscription incorporates the coin’s official:
£100
denomination.
This portrait was introduced to UK coinage in 2015 and remained the definitive Queen Elizabeth II effigy through the final years of her reign.
⸻
One Troy Ounce of 999.9 Fine Gold
The 2017 Britannia £100 Gold Proof is struck from:
999.9 Fine Gold
and contains approximately:
1 Troy Ounce of Fine Gold
with an official weight of:
31.210g
and diameter of:
32.69mm.
The coin therefore combines a full one-ounce gold format with Proof manufacture, a special anniversary design and an extremely small authorised mintage.
⸻
Proof Quality
The 2017 1oz Gold Britannia offered here was produced to:
Proof
quality.
The Royal Mint confirms Proof as the official striking standard for the anniversary Gold Proof collection.
Proof coins are specially produced for the collector market, creating sharply defined design elements and highly reflective surfaces.
That distinction is particularly relevant to this example because NGC has additionally awarded the coin its:
ULTRA CAMEO
designation.
⸻
NGC PF70 Ultra Cameo
This particular example has been independently authenticated, encapsulated and graded by NGC as:
PF70 ULTRA CAMEO
PF70 represents the highest numerical Proof grade on NGC’s 70-point grading scale.
The Ultra Cameo designation identifies the strong visual contrast between the frosted devices and mirrored fields of a Proof coin.
This example therefore combines:
NGC’s highest numerical Proof grade
with:
NGC’s Ultra Cameo designation
There is no numerical grade higher than 70.
⸻
NGC Population – Just 15 in PF70 Ultra Cameo
At the time of checking on 30 August 2026, the NGC certification evidence supplied for the exact:
2017 G. Britain Britannia 30th Anniversary Privy G100P
records:
NGC PF70 Ultra Cameo Population: 15
Higher Grades: 0
NGC Top Pop
For clarity:
Maximum Coin Mintage: 280
Reported Actual Mintage: 264
NGC PF70 Ultra Cameo Population: 15
Higher Grades: 0
Status: Top Pop
These figures measure different things.
The 280 is The Royal Mint’s official Maximum Coin Mintage.
The 264 is the reported actual mintage.
The 15 is the NGC PF70 Ultra Cameo population displayed at the time of checking.
NGC Census figures can change as further examples are submitted and certified.
