1 Sovereign - Charles III Bullion

Charles III sovereigns follow an unbroken legal framework stretching back to the Coinage Act of 1816, which fixed the sovereign's gold content and established it as the cornerstone of the gold standard Britain would anchor international trade to for the next century. The design lineage is similarly continuous — Benedetto Pistrucci's St. George reverse, cut in 1817, remains in use, making this one of the longest-running die designs in world coinage history.

Pistrucci, an Italian cameo cutter who was never granted British citizenship, was consequently barred from engraving the official coronation medal — yet his coin design outlasted every artist who replaced him.
