The 100th anniversary of the first blood transfusion in Slovakia. The design features an equilateral cross as an internationally recognised symbol of medical aid, hope and humanity. Inscribed in each arm is one of the four blood groups: A, B, 0, and AB. Incused within the cross are two more equilateral crosses, one within the other, with a drop of blood appearing at the centre of this image. Depicted around the central cross are the equally spaced lower parts of eight test tubes, each containing an incused stylised blood drop. Between each tube is a blood drop in relief. To the right of the bottom tube are the stylised initials ‘MP’, referring to the national side’s designer Maria Poldaufova; to the left is the mint mark of the Kremnica Mint (Mincovna Kremnica), consisting of the letters ‘MK’ placed between two dies.
