1 écu Europa - Adhésion de l'Espagne et du Portugal 1987 - or

The 1987 écu gold commemorative marks Spain and Portugal's accession to the European Communities on 1 January 1986 — the largest single enlargement the bloc had achieved to that point, bringing membership from ten to twelve nations. France issued this piece under the broader Europa coin program, a multinational series launched in 1961 by a consortium of European mints to promote integration through collector coinage before such symbolism became routine policy.

The .920 fineness is a deliberate throwback to the old Latin Monetary Union standard, which France, Belgium, Italy, and Switzerland had formally abandoned decades earlier.
