300 Dollars - Elizabeth II Maple Leaf Forever

The Maple Leaf Forever series draws on a long-standing Royal Canadian Mint tradition of issuing platinum bullion and collector strikes that track closely with industrial platinum demand — a metal Canada has never mined in significant quantities, relying instead on refinery relationships with South African and Russian producers. By 2019, platinum was trading well below gold for the first time in decades, a sustained inversion that made high-denomination platinum collector issues an increasingly awkward proposition for any mint.
