Description: 2009 coincides with the World Year of Astronomy but also with the 40th anniversary of the first steps on the Moon by Neil Armstrong. This double occasion allows the Monnaie de Paris to edit a coin enhanced with a surprising technological innovation: the first bombed piece representing the lunar relief on its convex reverse, with a celestial vault in blue gold.
