10 Pence - Charles III Crab Spider

Guernsey has issued wildlife-themed decimal coinage intermittently since the 1980s, operating outside the UK's Royal Mint agreements and free to select its own reverse subjects. The crab spider — ambush predators that change colour to match flowers — is an unusual choice for circulating coinage, appearing here as part of a broader fauna series rather than any commemorative programme. Whether these actually circulate in meaningful numbers or go directly into collector packaging is a question Guernsey's small population largely answers by default.
