10 Pence - Charles III Eurasian Hobby

Guernsey has issued its own coinage distinct from UK legal tender since the 19th century, operating under a currency agreement that keeps the Guernsey pound at parity with sterling while allowing the island's government to pocket seigniorage revenue from its own issues. The 2023 definitive series introduced wildlife subjects across denominations — a departure from the portrait-only reverses of earlier Guernsey decimal coinage.

The Eurasian hobby is a summer visitor to the British Isles, arriving from sub-Saharan Africa. Its presence on a Guernsey coin is a minor ornithological point of interest: the species breeds rarely on the island itself.
