WHY COLLECT THIS COIN
The 2023 Coronation Gold Proof Coin commemorates the first British coronation in nearly three generations, a rare historical milestone following the passing of Queen Elizabeth II in 2022. Its design, combining regal symbolism with artistic excellence, captures the significance of King Charles III’s accession to the throne and the continuity of the British monarchy.
With just 685 coins issued, this is one of the lowest-mintage modern UK proof coins, making PF70 Ultra Cameo examples especially scarce and sought after by advanced collectors. The combination of pure gold content, top grade, limited mintage and historic significance positions this coin as a standout piece for both numismatic collections and long-term holdings.
