10 Euros - Albert II Treaty of Rome

The 2007 Belgian commemorative marks the 50th anniversary of the Treaty of Rome, signed on March 25, 1957, which established the European Economic Community and Euratom. Belgium holds particular claim to that moment — Paul-Henri Spaak, the Belgian foreign minister, was one of the chief architects of the negotiations, and the treaty itself was signed in Rome's Palazzo dei Conservatori partly through his relentless diplomatic maneuvering in the preceding Messina and Venice conferences.

Several eurozone mints issued concurrent commemoratives for the same anniversary, making national comparisons across the series a minor collecting discipline of its own.
