History
Luxembourg is among the six signatories of the Treaty of Rome, in 1957: a small founding country, which mints its version of the 50th-anniversary coin in 2007.
For the 50th anniversary, thirteen countries strike the same design. Luxembourg adds a latent image of Grand Duke Henri, who ascended the throne in 2000, as Luxembourgish law mandates the sovereign's effigy on its coins.
The coin is struck by the Monnaie de Paris, hence the letter F, for France, within the star at the bottom right of the outer ring.
