2026 Gold Proof Reverse Frosted Sovereign with Box & Coa

An innovative first for the Sovereign series, the 2026 reverse frosted proof Sovereign reimagines The Royal Mint’s flagship coin with a striking new finish. Unlike traditional proof Sovereigns, which pair frosted motifs with mirrored fields, this groundbreaking edition inverts the effect: the background is frosted while the designs gleam with a polished brilliance. Each of these 2026 Sovereigns is struck in 22-carat yellow gold, restoring the rich tone seen on historic 19th-century Sovereigns. The obverse bears Martin Jennings’ definitive portrait of King Charles III, while the reverse revives Benedetto Pistrucci’s legendary Saint George and the dragon design. From a limited edition of just 3,000 pieces
