1 Penny - Edward IV Three crowns, Dublin

Edward IV's first reign saw a deliberate effort to stabilize Irish coinage after decades of debasement under Henry VI, though the Dublin mint's output remained chronically underweight by English standards. These pennies were struck during a narrow window before the 1463 recoinage reforms tightened control over Irish minting, making the full 1460–1463 range collectively scarce despite spanning multiple die pairings covered by Spink 6276–6280.
