1 Cent Essai Pattern Probe Test

In 2004, the European Commission mandated a series of euro cent test strikes produced in the coinage compositions and dimensions proposed for potential eurozone adoption. Guernsey, as a Crown Dependency, was never a candidate for actual euro adoption, but several territories and prospective member states participated in the broader pattern-striking exercise. Most of these essais were distributed exclusively to mint officials, collectors, and monetary authorities — circulation was never intended.
