500 Pounds - Charles III St George & The Dragon, Silver Proof

The 500-pound denomination exists purely as a vehicle for this format — a kilo of fine silver at 100mm is the Royal Mint's largest standard proof configuration, and attaching face value to it is a legal formality rather than a monetary reality. What matters here is the St George commission: the Mint has returned to this subject repeatedly since Benedetto Pistrucci's original 1817 design, and the tension between honoring that template and refreshing it for a new reign has defined every modern iteration of the type.

Charles III's accession in 2022 triggered a full redesign cycle across all denominations, with effigy and reverse pairings reconsidered for the first time in seventy years.
