50 Pence - Charles III King's First Year - Coronation, Silver Proof Gold gilded

Charles III's coronation on 6 May 2023 was the first British coronation in seventy years, and the Isle of Man — a Crown dependency with its own coinage rights — moved quickly to issue commemorative pieces under its own authority rather than waiting on the Royal Mint. The selective gilding technique applied here, isolating 24-carat gold plating over specific design elements on a sterling flan, requires a secondary electroplating stage after striking — a process that adds cost but has become increasingly common in modern proof commemorative production.
