Obverse: On the obverse, along the spiral of a one-meter-long strip, the inscriptions are arranged in a semicircle: LIETUVA, the logo of the Lithuanian Mint, and the year 2025. Below the center is the denomination – 20 €.
Reverse: The reverse continues the composition on the one-meter-long spiral strip, symbolizing the concept of measurement and Burattini's ideas. The design is harmoniously arranged around the central hole, emphasizing symmetry and the coin's unique shape.
About the coin: The coin is shaped as a circle made from a spiral-wound strip with a hole in the center. Diameter – 38.61 mm. It is struck from a 995 mm long strip, symbolizing the length of the universal measure – the meter – according to T. L. Burattini's work Misura Universale. Tito Livio Burattini (1617–1682), an Italian scholar who oversaw the mints of the Polish–Lithuanian Commonwealth, was the first to propose linking a unit of length to time and used the term metro cattolico to define standard measures in a booklet published in Vilnius in 1675. He took the Greek word metron, meaning measure, and created the word meter.
