Design & Artistic Features
-
The Reverse: A masterclass in modern minting technology, the reverse depicts an above-and-below-water confrontation. Massive, powerful tentacles—accentuated by smooth, translucent colored enamel—burst upward from the ocean depths to crush wooden pirate vessels. Swirling debris, churning waves, and a torn ship’s flag with an inverted inscription amplify the chaotic, high-stakes atmosphere.
-
The Obverse: Features the official effigy of His Majesty King Charles III in left-profile relief, artfully framed against a detailed background texture of oceanic seashells.
-
The Finish: The combination of an Antique Finish and Ultra High Relief (UHR) gives the metal an aged, tactile depth, making the physical anatomy of the monster and the tumultuous waves pop visually.
