The Czech heavyweight coin is (since of January 2019) the largest gold coin in the European Union and the second largest gold coin in the world. The coin was produced to celebrate the 100th anniversary of the Czechoslovak crown and has a nominal value of CZK 100 million. Pictures on both sides of the coin were designed by academic sculptor and medalist Vladimír Oppl. On the front side of coin, the birth of the Czech crown is symbolized by the 1919 stamp and the present epoch is symbolised by the logo of the Czech National Bank. On the reverse side is a Czech lion and the motif of the most famous Czechoslovak single-crown coin from 1922.
