Celebrating 350 Years of Innovation and Exploration

In 1675, King Charles II commissioned the Royal Observatory at Greenwich, unknowingly setting in motion centuries of astronomical discovery, navigational breakthroughs and global timekeeping.

Greenwich is where East meets West, and home to the Prime Meridian – an invisible line that runs through the very ground. The Royal Observatory is where Greenwich Mean Time was born, and it’s been guiding explorers, scientists and seafarers ever since.

Now, 350 years on, this iconic institution has been honoured on a UK £2 coin.

A Design Packed with Symbolism

Created by renowned designer Henry Gray, the reverse design of the 2025 Royal Greenwich Observatory £2 is a treasure trove for collectors.

Here’s what you’ll spot:

  • The Shepherd Gate Clock – one of the world’s first public displays of Greenwich Mean Time.
  • Ursa Minor and Polaris – the constellation and star used for celestial navigation across centuries.
  • The Prime Meridian on a globe – marking the division between East and West.
  • And along the edge, the words: “PERFECTING THE ART OF NAVIGATION” – a phrase taken from the Observatory’s founding Royal Warrant.

Every detail speaks to the Observatory’s unmatched contribution to science, timekeeping, and navigation.

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:

Left: The Royal Arms £1 was issued in 1983, 1993, 2003 and 2008
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.
