The 2021 1oz Silver Britannia Bullion Coin is one of the most important modern dates in the series because it introduced The Royal Mint's enhanced security-feature design. Struck from one troy ounce of .999 fine silver, it combines bullion value with a more technically advanced reverse.
The reverse includes details such as a latent image, surface animation, tincture lines and micro-text around the Britannia design. The obverse carries Queen Elizabeth II's portrait, placing the coin in the final years of her reign.
The 2021 issue is widely collected as the beginning of the security-feature era and is a key date for anyone building a modern Silver Britannia bullion run.
