On the coin, the text "ART NOUVEAU" is located at the top. Below and around it is a detail of the façade of the Hotel van Eetvelde, a wall mosaic by Victor Horta. On the left, the mark (an Erlenmeyer flask with an aster) and the mark of the Royal Dutch Mint (the Mercury rod). Next to it, the indication of the country BE and the year 2023, on the right "IB" (the initials of the designer Iris Bruijns).

The design expresses the asymmetrical composition typical of Art Nouveau. The elegant play of lines creates a clear connection with nature. With a little imagination, an iris flower can be seen, creating a visible connection with the designer Iris Bruijns.
