2018 Possum Magic Baby Proof Coin Set. Since the publication of Possum Magic in 1983, Mem Fox's lyrical prose and Jule Vivas' whimsical illustrations have captured the imaginations of young Australian readers. In 2018, as the book celebrates its 35th birthday, this delightful tale is a fitting theme for the Royal Australian Mint's baby set which, like Possum Magic, celebrates the wonders of Australia and the importance of love and family. Featuring a special coloured printed proof 50 cent coin to celebrate one of the book's beautiful illustrations. Please contact Adelaide Exchange Jewellers to find out more on this item.
