10 Pence - Charles III Border Collie, Colored

Guernsey's decimal coinage has always operated at arm's length from the Royal Mint, with the island's Treasury commissioning its own designs independently under Crown dependency status. This colored 10 pence is part of a broader British Isles dog breeds series that several Crown dependencies and overseas territories have leaned into heavily since the mid-2010s — a format that sells well to thematic collectors and barely circulates at all.
