Description : The United Nations Charter was finalised at the Yalta Conference and signed by 50 states at the San Francisco Conference on the 26th of June 1945. New York became the seat of the organisation. As a symbol of the United Nations flag, the coin shows the globe with the entire land mass inhabited by humans, framed by two olive branches, the classic symbol of peace. In the centre is the geographic North Pole and around it the continents of the northern hemisphere; the southern hemisphere ‐ without Antarctica ‐ is distorted by the projection resembling a mid‐distance azimuthal projection and is shown too large in area. The year of issue "2020" and "PORTUGAL" are written in irregular, handwriting‐like characters at the top, and the occasion of issue "UN / ONU 75 YEARS / ANOS" (United Nations 75 Years) is written bilingually in English and Portuguese below. On the left is the mint mark "CASA DA MOEDA" of the Portuguese mint Imprensa Nacional‐ Casa da Moeda S.A. in Lisbon in two lines and on the right ‐ also in two lines ‐ the name of the coin designer "ANDRÉ LETRIA".
