CREEKRATS GOLD · BULLION COIN GUIDE
British Britannia.
A flagship British bullion coin since 1987, now struck in .9999 fine gold and protected by four advanced visual security features.
THE ESSENTIALS
A familiar symbol with a specification that changed.
Current specifications shown for the standard one-ounce Gold Britannia. Earlier dates require date-appropriate purity and design checks.
THE PURITY CHANGE
Two metal standards sit behind the same name.
Gold Britannias dated from 1987 through 2012 were struck in 22-karat gold. From 2013, The Royal Mint increased the gold coin’s fineness to 999.9, commonly described as 24 karat.
Both generations contain their stated quantity of fine gold. The distinction matters for gross weight, colour, handling and authentication, so the date should always be part of the specification check.
FOUR VISUAL SECURITY FEATURES
Decoration that changes as the coin moves.
Latent image
A small device changes between Britannia’s trident and a padlock when the viewing angle changes.
Surface animation
Fine background details create the impression of waves moving behind Britannia as the coin rotates.
Micro-text
The border carries DECUS ET TUTAMEN, meaning “an ornament and a safeguard”, in very small lettering.
Tincture lines
Traditional line patterns define the Union flag on Britannia’s shield and add difficult-to-reproduce detail.
These features belong to the modern design. Their absence on an older genuine Britannia is not evidence of a counterfeit; always compare like date with like date.
READING THE COIN
A changing monarch. An enduring guardian.
CURRENT OBVERSE
King Charles III
Current Britannias carry Martin Jennings’ definitive coinage portrait of King Charles III. Earlier coins show the date-appropriate portrait of Queen Elizabeth II.
REVERSE
Philip Nathan’s Britannia
Britannia stands with helmet, trident and shield: protection, maritime identity and national continuity expressed through a modern design created in 1987.
The monarch and portrait change with the issuing period. A buyer should match the year, obverse portrait, purity and reverse security treatment rather than relying on one universal reference image.
CURRENT GOLD SIZES
One ounce and three fractional choices.
Fractional Britannias reduce the purchase amount per coin but commonly carry a higher premium per ounce. Confirm the exact year and product specification before buying.
Face values establish legal-tender status; they do not represent the coins’ metal or market value.
WHICH BRITANNIA?
Date, purity and finish define the product.
CURRENT BULLION
Modern 24-karat Britannia
Coins from 2013 onward contain 999.9 fine gold. Modern issues combine the established reverse with advanced visual security and date-appropriate royal portraiture.
EARLIER OR COLLECTOR PRODUCT
22-karat and proof Britannias
Pre-2013 bullion coins use the earlier 22-karat standard, while proof and special editions may add finish, rarity or presentation premiums beyond their gold content.
BEFORE YOU BUY
Match the price to the exact Britannia.
Date and purity
Confirm whether the coin belongs to the 22-karat or 999.9-fine generation.
Premium
Compare the selling price with the live value of the stated fine-gold content.
Buyback spread
Ask what the same dealer would pay for the same size, year range and finish today.
Security generation
Expect the four advanced features only on modern issues that were designed to carry them.
Condition and finish
Distinguish ordinary bullion condition from proof, special finish or graded presentation.
Local liquidity
Compare dealer recognition and buyback terms in the market where you expect to sell.
A MODERN BRITISH BULLION STANDARD
Britannia became the face of British bullion in 1987.
The Royal Mint launched the £100 one-ounce Gold Britannia in 1987, using Philip Nathan’s new interpretation of the historic female personification of Britain.
Silver Britannias followed in 1997 and platinum in 2007. Gold purity moved from the original 22-karat standard to 999.9 fine gold in 2013.
The reverse has evolved through increasingly sophisticated surface detail, while the obverse records the changing monarch. Britannias dated 2023 mark the transition from Queen Elizabeth II to King Charles III portraits.
