The design reverts to the 1930 design, probably due to the fact that Bulgaria and the United Kingdom were on different sides during World War II so Bulgaria could not continue mintage at the Royal Mint London as in 1934.
The edge of the coin carries the inscription "БОЖЕ ПАЗИ БЪЛГАРИЯ" - God Save Bulgaria.
Effigy of King Boris III facing left (by Lajos Berán), artist's name L. Berán in small letters under the truncation of the neck. Around, БОРИСЪ III ЦАРЬ НА БЪЛГАРИТѢ (Boris III, King of the Bulgarians). Below, mint mark A of the Berlin Mint.
