Description

Guglielmo Giovanni Maria Marconi (1874–1937) was an Italian inventor and electrical engineer, known for his creation of a practical radio wave-based wireless telegraph system. This led to Marconi being credited as the inventor of radio, and he shared the 1909 Nobel Prize in Physics with Karl Ferdinand Braun "in recognition of their contributions to the development of wireless telegraphy".

The collector coin is part of the Europa Coin Programme, also known as the European Silver Programme, or the Eurostar Programme. It is an initiative dedicated to the issuance of collector-oriented legal tender coins in precious metals to celebrate European identity. The issuing authorities of EU member countries voluntarily contribute coins to the Europa Coin Programme. Multiple countries have participated in the programme, beginning in 2004. Some coins are denominated in euro, others are denominated in other currencies.

Portrait of Guglielmo Marconi inspired by a period image; on the left, in the background, the yacht and floating laboratory "Elettra". Below the portrait, in exergue, the signature of Marconi and below the name of the engraver.

Elettra was the name of Guglielmo Marconi's steam yacht – a seaborne laboratory – from which he conducted his many experiments with wireless telegraphy, wireless telephony and other communication and direction-finding techniques during the inter-war period.
