2019 - $20 - 1 oz. Pure Silver Coloured Coin - 100th Anniversary of the First Non-Stop Transatlantic Flight

On June 14, 1919, a modified First World War Vickers Vimy bomber lifted off from St. John's, Newfoundland and flew straight into the history books. British aviators John Alcock and Arthur Whitten Brown persevered through a rough takeoff, equipment failures, fog, ice and snow before crash-landing the next day in County Galway, Ireland. In doing so, they became the first aviators to cross the Atlantic Ocean in less than 72 consecutive hours—a new milestone in aviation history. In 1969, Canada Post issued a 15-cent stamp to commemorate the 50th anniversary of the first non-stop transatlantic flight. Now, 50 years after that special issue—and on the centennial of this aviation first—the Canadian stamp is forever immortalized on this stamp-shaped, 99.99% fine silver coin.
