The £5 Coin Celebrating 350 Years of the Royal Observatory Greenwich

The Royal Observatory Greenwich is one of Britain’s greatest scientific landmarks. Established in 1675, it became the cornerstone for global navigation and timekeeping. And now, this remarkable legacy is captured in an equally remarkable £5 coin — a design that pays tribute to centuries of exploration, astronomy, and engineering.

Whether you’re a passionate numismatist or simply intrigued by the wonders of science, this coin is worth a closer look.


A Landmark in British Coin Design

At first glance, this isn’t just a commemorative piece — it’s a statement of precision. The design is deeply symbolic, dividing the surface into two distinct yet interconnected halves.

Running vertically through the centre is the Prime Meridian, the global reference point for time and space, originating at Greenwich. This bold line doesn’t just split the coin — it connects hemispheres and disciplines.

East: Gazing Upwards

On one side, the emphasis is celestial. The Great Equatorial Telescope dome of the Royal Observatory rises beneath a starry sky, where Ursa Minor and the North Star remind us of centuries of cosmic observation and navigation.

West: Mastering Time

Opposite, the design moves from stars to seconds. Intricate mechanisms represent Clock B, a pioneering free-swinging pendulum clock by Martin Burgess, renowned for its unmatched accuracy. It’s a tribute to human ingenuity — where measuring time became an art and a science.

The Dambusters Raid: A Defining Moment of WWII History

In the dark early hours of May 16-17, 1943, a daring mission was underway—one that would change the course of the Second World War and etch the name “Dambusters” into military history.

Known as Operation Chastise, this audacious air raid targeted key German dams, aiming to cripple the industrial heartland of the Ruhr Valley. Now, over 80 years later, we continue to honour the courage and sacrifice of the men who took part in one of the most iconic operations of the Second World War.

What Was the Dambusters Raid?

Led by Wing Commander Guy Gibson, 133 aircrew from the Royal Air Force’s newly formed 617 Squadron flew specially modified Lancaster bombers deep into enemy territory. Their mission: destroy the Möhne, Eder, and Sorpe dams using a revolutionary new weapon—the “bouncing bomb,” designed by British engineer Barnes Wallis.

These bombs skipped across the surface of the water, bypassing torpedo nets, before detonating against the dam walls. The operation was incredibly risky, requiring precise flying at just 60 feet above the water under heavy enemy fire. The result was devastating: the Möhne and Eder dams were breached, flooding the surrounding countryside and causing significant disruption to German industry.

Although the raid came at a cost—53 airmen lost their lives—the bravery and ingenuity displayed left an indelible mark on military history.

A Rare Chance to Own a Piece of Dambusters History

To commemorate this heroic operation, two remarkable collectors’ items have been released—perfect for any WWII enthusiast or collector.

A Royal Milestone in Coinage: The Coat of Arms of His Majesty King Charles III

On 8 September 2022, following the passing of Queen Elizabeth II, His Majesty King Charles III acceded to the throne — a moment that marked both reflection and renewal for the British monarchy. Now, in 2025, a major numismatic milestone marks this new reign: the first UK coin to feature the Royal Coat of Arms of King Charles III.

More than just a design, the Royal Arms are a time-honoured symbol of monarchy and national authority — and this historic debut offers collectors a once-in-a-generation opportunity to own a significant artefact of royal transition.


The Royal Arms Reimagined

For more than a thousand years, the Royal Arms have symbolised the authority, heritage, and continuity of the British Crown. Displayed on official state documents, courtrooms, government buildings, and even British passports, this heraldic emblem embodies the unity and sovereignty of the realm.

During Queen Elizabeth II’s reign (1952–2022), her Royal Arms were ever-present and, at times, even appeared on coinage. Yet, this is the first time the personal Royal Coat of Arms of King Charles III has featured on a UK coin, offering a powerful expression of royal continuity and modern monarchy.

The 2025 Coat of Arms £5 coin showcases a newly commissioned design by Timothy Noad, one of Britain’s most celebrated heraldic artists. His interpretation honours the enduring traditions of the monarchy while introducing elegant modern detail.

Key elements of the design include:

  • The crowned shield, representing the nations of the UK
  • The lion of England and unicorn of Scotland as noble supporters
  • Heraldic flourishes symbolising duty, unity, and royal heritage

It is a timeless composition that reflects His Majesty’s lifelong commitment to tradition, the environment, and public service.


A History of Royal Arms on UK Coinage

While this is the first appearance of King Charles III’s Royal Arms, it joins a respected legacy of coinage bearing royal heraldry.

Under Queen Elizabeth II, the Royal Arms first appeared on the inaugural £1 coin, introduced in 1983 to replace the paper £1 note. The design by Eric Sewell, then Chief Engraver at the Royal Mint, featured a stylised version of Her Late Majesty’s Arms and became one of the most recognisable modern coin motifs.

The Royal Arms £1 was issued in:

Right: The 2015 Royal Coat of Arms £1 was one of the last commemorative round pound designs
  • 1983 – the very first year of the £1 coin
  • 1993, 2003, and 2008 – each marking notable updates or anniversaries

In 2015, Timothy Noad was once again called upon to reimagine the Royal Arms for a commemorative issue of the round pound. Although that design did not enter circulation, it remains one of the last and most admired heraldic designs issued before the £1 coin was reshaped into its current 12-sided form.

The 2025 £5 release, therefore, represents not just a first for King Charles III, but also a historic continuation of the Royal Arms tradition on UK coinage — deeply valued by collectors with a passion for royal and constitutional heritage.
