10 Pence - Charles III Common Lizard, Colourised

Guernsey has issued colourised circulation-format coins sporadically since the early 2000s, though pieces like this one occupy an awkward commercial middle ground — too novelty-adjacent for serious type collectors, too denomination-specific to be purely commemorative. The common lizard, Zootoca vivipara, is one of the few reptile species native to the British Isles and is notably viviparous in cooler northern climates despite being oviparous in warmer southern populations — an unusual reproductive flexibility that makes it genuinely interesting subject matter, whatever one thinks of the colourisation technique.
