The Italian 20-cent coin shows the sculpture Unique Forms of Continuity in Space (1913) by Umberto Boccioni. In this work, he tries to resolve in sculptural form the problem of showing movement. The sculpture shows a human figure going forward in powerful steps. The design on the coin is by Maria Angela Cassol.
Euro coins and banknotes were introduced on 1 January 2002 in twelve countries. Today, the euro area has grown to include 18 countries. Euro coins feature a common design on one side.
