10 Pence - Charles III Red Gurnard; Colourised

Guernsey's fish-themed circulating coinage series predates this issue by decades, with the bailiwick having long used native Atlantic species as design subjects — a practical assertion of island identity within British isles coinage rather than any formal monetary independence. The red gurnard, a bottom-dwelling coastal fish common in Channel Island waters, was a staple catch for Guernsey fishermen before industrial trawling collapsed inshore stocks across the English Channel.

The selective colorization is applied post-strike using pad-printing ink, a process increasingly used by smaller issuing authorities to differentiate collector-oriented pieces from standard circulation without retooling dies.
