An ultra-rarity in modern British Numismatics.
This 2023 1/4oz Gold Proof Britannia is not merely a collector’s piece; it is a physical participant in one of the United Kingdom’s oldest and most prestigious judicial ceremonies. This specific coin was selected from the production line for the Trial of the Pyx - the rigorous independent testing process held at Goldsmiths' Hall to ensure the absolute integrity, purity, and weight of the nation's coinage.
While standard Proof Britannia's are highly sought after, this specimen is one of only 10 pieces designated for the Trial. This makes it significantly rarer than almost any other modern gold issue, representing a "top-tier" acquisition for the serious investor.
The Pyx Pedigree
- Extreme Rarity: A strictly limited mintage of just 10 specimens.
- Judicial Provenance: Authenticated as a coin personally handled by the Jury of the Goldsmiths’ Company.
- 24-Carat Excellence: Struck in .9999 fine gold to the highest Proof standard.
- First Portrait: Features the first definitive coinage portrait of His Majesty King Charles III by Martin Jennings.
Presentation & Documentation
This rarity is housed in its original Royal Mint luxury presentation case. It is accompanied by the specialized Trial of the Pyx Certificate of Authenticity and a historical booklet detailing the 700-year-old ceremony - essential documentation that preserves its unique provenance for future generations.
As a 24ct gold coin, this item is VAT-free and qualifies for Capital Gains Tax (CGT) exemption, making it as strategically sound for an investment portfolio as it is prestigious for a numismatic collection.
