1 Penny - Elizabeth II 2nd portrait

Jersey switched from bronze to copper-plated steel for its penny coinage in 1992, a cost-driven decision that followed similar moves by the UK and other Commonwealth issuers as copper prices made the old alloy increasingly uneconomical. The magnetic planchet change is the defining distinction of the KM#54b type from its predecessors, and the shift created immediate practical consequences — these coins are retrievable by magnet, unlike the earlier bronze issues.
