Ecu
The term écu may refer to one of several French coins. The first écu was a gold coin minted during the reign of Louis IX of France, in 1266. Écu means shield, and the coin was so called because its design included a shield bearing a coat of arms. The word is related to scudo and escudo. The value of the écu varied considerably over time, and silver coins were also introduced.The above text is a snippet from Wikipedia: Ecu
