The reverse features Philip Nathan’s standing Britannia wearing a Corinthian helmet and holding a trident, Union Flag shield and olive branch. The surrounding inscriptions record the Britannia name, year, one-ounce weight and .999 silver fineness. The obverse carries Martin Jennings’ first uncrowned coinage portrait of King Charles III. The advanced-security reverse combines a latent trident-to-padlock image, animated waves, DECUS ET TUTAMEN micro-text and tincture lines on Britannia’s shield. The obverse carries the first uncrowned King Charles III portrait by Martin Jennings.

The Silver Britannia was introduced by The Royal Mint in 1997, ten years after the first Gold Britannia. Since 2013, the one-ounce silver bullion coin has been struck from .999 fine silver. Philip Nathan’s standing Britannia remains the defining image of the bullion series, combining her trident, Union Flag shield and olive branch as symbols of maritime strength, national identity and peace.

This is the standard 2023 King Charles III bullion Britannia featuring Martin Jennings’ first uncrowned portrait. It is the second principal Britannia bullion issue dated 2023 and must not be confused with either the Queen Elizabeth II version or the separate crowned Coronation Britannia. No fixed maximum mintage was declared.
