The medal features a profile of Nevanlinna, the text "Rolf Nevanlinna Prize", and very small characters "RH 83" on its obverse. RH refers to Raimo Heino, the medal's designer, and 83 to the year of first minting. On the reverse, two figures related to the University of Helsinki, the prize sponsor, are engraved. The rim bears the name of the prizewinner.
