1 Dollar - Elizabeth II Diamond Wedding - Elizabeth in green coat and hat, Phillip in red uniform

Issued to mark the 60th wedding anniversary of Elizabeth II and Prince Philip in 2007, this Cook Islands piece is one of hundreds of commemorative dollars the territory has produced as licensed revenue issues — coins minted primarily for the collector market with no meaningful circulation history. The Diamond Wedding series spawned numerous variants across multiple issuing authorities, few of which have any direct connection to the events they commemorate.
