The year 2020 was marked by the global health crisis related to covid-19. The obverse of the coin represents the figuration of the human in union, represented by a face inscribed in a sphere. It faces the infinitely small, represented by fragments of DNA inscribed in a circle. By its oblique axis, this allegory represents the research and its intelligence dominating the infinitely small; studying it and triumphing over the diseases. Monnaie de Paris has developed 3 blister packs that bring out the main feelings that emerge from this crisis, the blisters “UNION”, “HEROS” and MERCI.
