5 Dollars - Elizabeth II Royal Wedding

Issued to mark the April 2005 marriage of Charles, Prince of Wales, to Camilla Parker Bowles — a union that had been legally impossible under earlier interpretations of the Royal Marriages Act 1772 and required a specific government legal opinion to proceed. The wedding itself was delayed by one day, from April 8 to April 9, to allow attendance at Pope John Paul II's funeral in Rome.

Cook Islands has issued commemorative five-dollar silver pieces under licensing arrangements for decades, with this piece falling squarely within that program rather than reflecting any domestic monetary need.
