5 Pounds - Elizabeth II Four Generations of Royalty, Silver Proof

Issued to mark a photograph taken by Annie Leibovitz in April 2016 — the only officially sanctioned image ever to show four simultaneous generations of the British line of succession — this coin commemorates a moment that required coordinating the schedules of the Queen, Prince Charles, Prince William, and a then-infant Prince George. The Royal Mint released the piece in 2018, two years after the photograph, tying it to no specific anniversary with any particular precision.
