10 Pence - Elizabeth II Common Blue, Colourised

Guernsey has operated as a Crown Dependency with its own independent currency since well before decimalization, and its coinage — while legal tender locally — has never circulated in the United Kingdom. The "Common Blue" belongs to a butterfly series issued by the Bailiwick, a format that has become a reliable revenue stream through collector sales rather than circulation. Colourised issues of this type are typically applied after striking via a pad-printing process and are produced in quantities calibrated entirely to philatelic and numismatic demand, not monetary need.
