1 Crown - Edward VIII

Edward VIII abdicated in December 1936 before any circulating coinage bearing his effigy entered production, making him the only 20th-century British monarch with no official circulation issue. This 1987 piece is a retrospective strike issued decades after his reign, part of a wave of collector interest in the abdication gap. The Royal Mint had actually prepared pattern coins in 1936 — those originals are museum pieces — so all Edward VIII coins reaching the public market are later productions.
