A Coin That Redefines Modern Numismatics
Some coins mark history. Others become history.
The 2024 Great Britain £1,000 Gold Britannia & Liberty Kilo Proof does both. This extraordinary issue represents a turning point in modern coin design. It unites two of the most powerful national symbols ever struck on coinage.
Even more remarkably, the Royal Mint limited the mintage to just 10 pieces worldwide. That number alone places this coin among the rarest modern gold issues ever produced.
Now, an example graded NGC Proof-70 Ultra Cameo First Day of Issue, with a Gordon Summers-signed label, has surfaced at auction. It carries not only perfection, but also provenance.
A Historic First Between Two Great Mints
For the first time, the United States Mint and The Royal Mint created a single unified coin design.
This release anchors the 2024 Liberty and Britannia Program. The initiative celebrates the enduring “special relationship” between the United States and the United Kingdom.
Although both mints collaborated before, they never shared a fully integrated design on one coin—until now.
Chief Engravers Joseph Menna and Gordon Summers worked together to bring this vision to life. Their goal was clear: create a design that gives equal weight to both nations’ identities.
The Design: A Coin You Must Turn to Understand
At first glance, the design feels familiar. Then it surprises you.
The reverse presents Liberty and Britannia in a “playing card” format. The layout invites interaction. Rotate the coin 180 degrees, and the perspective shifts.
Britannia, designed by Summers, wears a Corinthian helmet and grips her trident.
Liberty, designed by Menna, carries a torch and wears a crown of stars.
Each figure stands upright depending on orientation. This duality is not decorative—it is intentional. Menna described the rotation as essential to fully experience the artwork.
The symbolism runs deep. Liberty reflects American ideals of freedom. Britannia represents British strength, unity, and maritime power dating back to the 17th century.
Together, they form a visual dialogue across the Atlantic.
The Obverse: A New Monarch
The obverse features the official portrait of King Charles III, created by Martin Jennings.
This portrait marks a new era in British coinage. It adds another layer of historical importance to an already groundbreaking release.
Extreme Rarity Meets Monumental Scale
This coin is not just rare, it is massive.
- Weight: 1 kilogram (32.282 troy ounces of gold)
- Purity: .9999 fine gold (24 karat)
- Face Value: £1,000
- Mintage: Only 10 pieces
The kilo format represents the pinnacle of the program. It stands as the most prestigious and limited version of the series.
Perfect Grade, Perfect Timing
This specific example achieved the highest possible certification from Numismatic Guaranty Company.
- Proof-70 Ultra Cameo: No imperfections, even under magnification
- First Day of Issue: Submitted within 24 hours of release
- Signed Label: Personally signed by Gordon Summers
These factors elevate the coin beyond rarity. They place it firmly in the category of elite modern numismatic trophies.
Presentation Worthy of the Coin
The Royal Mint designed the packaging to match the coin’s significance.
Collectors receive:
- Walnut-veneered presentation case with engraved Royal Mint branding
- Velvet-lined interior built to support the coin’s weight
- Numbered Certificate of Authenticity, matching the coin (this example: #2 of 10)
- Protective outer sleeve with Liberty and Britannia branding
However, the NGC-certified coin resides in an oversized holder. As a result, many collectors store the slab separately from the original case.
A Possible Link to an Ancient Tradition
Some examples from this program connect to the Trial of the Pyx, a centuries-old ceremony that tests coinage for purity.
If associated, this link adds historical depth. It ties a modern masterpiece to one of the oldest traditions in British numismatics.
Why This Coin Matters
This issue does more than showcase gold. It tells a story.
It represents:
- First-ever unified design between two global mints
- Celebration of shared democratic values
- Bold modern artistic approach to classical symbols
- Extreme rarity that few collectors will ever own
In short, it stands at the intersection of art, diplomacy, and numismatics.

What does the bidding start at? As if…
I love the idea of unity between nations in times like these. The story, playful design, perfection in strike, and mint limit really elevate this coin to a whole new level
Thought the design was cool. Feel like everyone lost interest in this coin pretty fast. What I thought was different was the UK and the USA had their own versions of the coin.
