Subject of the commemorative coin:
 20th anniversary of joining the OECD

 Description of the design:
 The upper right half of the design for the national side shows the concept of digital humanism: printed circuits in the shape of the human brain, with a circle in the middle representing a microprocessor. At the bottom right is the Slovak coat of arms. In a square that partially overlaps the main image are the words “20. VÝROCIE” and “VSTUP SR DO OECD” (20th anniversary of Slovakia’s accession to the OECD). Below the square is the name of the issuing country “SLOVENSKO” and below that the year of issuance “2020”. Between the square and the left edge of the design is the mint mark of the Kremnica Mint (Mincovna Kremnica), which consists of the letters “MK” between two dies. Below the mint mark are the stylized letters “PV”, referring to the designer Peter Valach. The outer ring of the coin features the twelve stars of the European flag.
