20 Pounds - Elizabeth II Platinum Jubilee - Four Graces

The "Four Graces" design by sculptor John Bergdahl was originally created for the 2022 UK Platinum Jubilee coinage program and became one of the most discussed royal portrait commissions in decades — notably for depicting Elizabeth II as a young woman surrounded by allegorical figures, a deliberate echo of the Thomas Bewick engraving that inspired it. Alderney, a Crown dependency outside the United Kingdom proper, has long issued commemorative silver in large formats under license, with pieces frequently struck by the Royal Mint or contracted partners to exacting specifications.

At 311 grams of .999 silver, this is essentially a 10-troy-ounce bullion-commemorative hybrid — collectible framing around a substantial silver position.
