Subject of the commemorative coin:
 150th Birthday of Josip Plemelj

 Description:
 The design shows parts of the equation that Josip Plemelj was the first to solve. Numbers and symbols rotate in circles that represent the rotation of the planets, the movement in space and the combination of separately unsolvable elements. In this way, Josip Plemelj’s two fields of expertise come together: mathematics and astronomy. The inscription “JOSIP PLEMELJ 1873”, the name of the issuing country “SLOVENIJA” and the year of issuance “2023” are also included in the design. The outer ring of the coin features the twelve stars of the European flag.
