About the 2026 5 oz Silver Britannia
The 2026 5 oz British Silver Britannia holds five troy ounces of .999 fine silver in a single coin from The Royal Mint, 63.75 mm across with a £10 face value. It carries the same Britannia and the same four security features as the 1 oz coin, on a face wide enough to see them without a loupe.
Nathan’s Britannia, Five Times Over
Philip Nathan’s 1987 Britannia strides forward across the reverse in helmet and flowing robes, with the Union Flag shield at her side and waves rolling in the background. Below her gown sits a trident for her ties to the sea. Around her runs the micro-text DECUS ET TUTAMEN, “an ornament and a safeguard”, which is the brief the security features were built to. The obverse carries Martin Jennings’s portrait of King Charles III.
Four Security Features on a Bigger Canvas
The Royal Mint calls the Britannia one of the most visually secure coins in the world, and four security features back that up. A latent image switches from a padlock to a trident as you tilt the coin. Surface animation makes the waves behind Britannia appear to move. Tincture lines pick out fine details such as the Union Flag on her shield, and the micro-text border works as decoration and protection at once. On a coin this size, every one of them is easy to check by eye.
Five Ounces in One Piece
A 5 oz coin is a convenient way to hold silver. It takes up one capsule instead of five separate coins, and big coins often carry a lower premium per ounce than the same silver in 1 oz pieces. The trade-off is that it sells whole, so you can’t sell off a single ounce. It is a bullion coin, bought for its silver and its design rather than a limited mintage.

2026 5 oz British Silver Britannia FAQ
How much silver is in the 5 oz Britannia?
Five troy ounces of .999 fine silver, which is about 155.5 grams of pure silver. That is five 1 oz Britannias’ worth of silver in one coin.
How big is the 5 oz Silver Britannia?
It measures 63.75 mm across, just over two and a half inches. The extra width gives the design and the security features room to show.
Why does it say £10 if it holds five ounces of silver?
The £10 face value is the denomination The Royal Mint gives the coin, and it has nothing to do with the coin’s worth. The silver inside is worth far more, so the coin is bought and sold on its metal.
How is the 5 oz Britannia packaged?
The Royal Mint issues each 5 oz Britannia in a single coin capsule, which protects the surfaces from handling.
How can I tell a 5 oz Britannia is genuine?
Tilt it. The latent image should switch between a padlock and a trident, and the waves should appear to move with surface animation. Then check the DECUS ET TUTAMEN micro-text around the border and the tincture lines on the shield.
