100 Dollars - Elizabeth II Repatriation of the Canadian Constitution

Canada's 1982 gold commemorative marks the patriation of the Constitution Act — the moment Canada finally severed its last legislative tie to the British Parliament after decades of failed negotiation. Pierre Trudeau had pursued patriation aggressively since the 1960s, and the final push in 1981–82 was politically fractious: Quebec never formally signed the agreement, a constitutional wound that remained open through the Meech Lake and Charlottetown failures that followed.

The Royal Canadian Mint struck these in .917 fine gold, the traditional crown gold standard. Issued in the same year the Constitution Act received Royal Assent — April 17, 1982.
