1 Penny - Edward IV 2nd reign, York mint

Edward IV's second reign saw York operating as a secondary mint largely to service the north of England, where London-struck coin was slow to circulate. The ecclesiastical authorities at York Minster held minting rights under the Archbishop, and pennies from this period carry a distinguishing mark of that arrangement — a key or other archiepiscopal symbol in the design that separates York product from the Tower mint's output. During this reign, Archbishop Neville's attainder in 1472 briefly complicated the mint's authority before George Neville's successor restored normal operations.

North 1645 covers several sub-varieties distinguished by mintmark sequence. Attribution to a precise emission within the 1471–83 range typically depends on die axis and punch details.
