The design depicts the Thessalonian brothers Constantine and Methodius along with the symbolic double cross stood on three hills. The cross is at the same time held as a Bishop's crozier, thereby linking together symbols of statehood and Christianity and emphasising the significance of the brothers' mission, which helped ensure the full sovereignty and legitimacy of Great Moravia — the first Slav state in central Europe. The figure of Constantine is holding a book representing education and faith, while Methodius is shown with a church symbolising faith and institutional Christianity. Along the lower edge of the inner part of the coin is the name of the issuing country ‘SLOVENSKO’, the year ‘863’ and the year ‘2013’, with a dividing mark between each. Along the upper edge of the inner part are the names ‘KONŠTANTÍN’ and ‘METOD’. To the left of the brothers are the stylised letters ‘mh’, the initials of the coin's designer Miroslav Hric, and to the right is the mint mark of the Kremnica Mint, comprising the letters ‘MK’ placed between two dies.
The coin’s outer ring depicts the 12 stars of the European flag.
