The 2026 Britannia KCIII 1oz Silver Coin contains one troy ounce of 999 fine silver, with King Charles III on the obverse and Philip Nathan’s Britannia on the reverse. It is UK legal tender with a £2 face value, so it is exempt from Capital Gains Tax for UK residents.

The 2026 Silver Britannia design

The Royal Mint describes the modern Britannia as the most visually secure coin in the world, combining Nathan’s design with four security features developed by the team behind the 12-sided £1 coin.

On the obverse, Martin Jennings’ uncrowned portrait of King Charles III faces left, opposite the direction Queen Elizabeth II faced.

Security features on the 2026 Britannia

• Latent image: a trident below Britannia’s gown becomes a padlock as the coin is tilted.
• Surface animation: the waves behind Britannia appear to move as the light changes.
• Micro-text: DECUS ET TUTAMEN, ‘an ornament and a safeguard’, runs around the design.
• Tincture lines: fine heraldic shading picks out the Union flag on Britannia’s shield.

Why buy a 2026 Silver Britannia?

The 2026 silver Britannia gives you a current-year coin with the full set of security features, which helps when you come to sell to a dealer or private buyer.

It is the most straightforward way for a UK buyer to hold silver without giving up the CGT exemption.

Why buy 1oz silver coins?

The one-ounce silver coin is the standard unit of the silver market, easy to value and easy to sell in any quantity. Silver costs a fraction of gold per coin, so it suits smaller or more frequent purchases, and a holding built from 1oz coins can be sold a coin at a time. Legal tender coins such as this one are exempt from Capital Gains Tax for UK residents.

Frequently asked questions

What makes the Britannia hard to counterfeit?

Four features work together: a latent image that switches between a trident and a padlock, moving surface animation, micro-text and tincture lines on the shield.

Is the 2026 coin different from the 2025 one?

The design, weight and purity are the same. The date is the difference, which matters mainly to collectors.
