The national side of the coin depicts the characteristic surroundings of Žuvintas Biosphere Reserve, which belongs to the World Network of Biosphere Reserves of UNESCO’s Man and the Biosphere Programme: remote islands of a unique bird lake and Lithuania’s largest wetland as well as its distinctive animals. In the foreground there is a great bittern reaching for a fire-bellied toad floating in the water. In rushes depicted on the right there is an aquatic warbler, above – a flock of common cranes and a mute swan, symbolising the establishment of the Reserve. The composition is surrounded by inscriptions LIETUVA (LITHUANIA), ŽUVINTAS, UNESCO, the year of issue (2021) and the mintmark of the Lithuanian Mint. The coin’s outer ring bears the 12 stars of the European Union flag.
