1 Dollar - Elizabeth II The 'Unsinkable' Molly Brown

Margaret Brown earned her "Molly" nickname posthumously — she was known as Maggie in her lifetime. The "unsinkable" epithet came from a 1960 Broadway musical, not from anything she or her contemporaries said. She survived the Titanic's sinking in April 1912, reportedly helping to manage Lifeboat 6 and pressuring the quartermaster to turn back for survivors, though accounts of her exact role vary considerably by source.

Cook Islands issued heavily in this period under licensing arrangements with foreign mints, with the gold-plated copper format common across dozens of commemorative subjects. The Titanic centenary in 2012 generated a notable surge in such issues from multiple issuers simultaneously.
