Such "abstract" themes are usually difficult for coins. How can a designer visualize human rights or the anniversary of a constitution? I still think that, of the four €2 coins issued to commemorate the Declaration of Human Rights, this one is the best design. Portugal is interesting (the 30 sheets below the country name are supposed to represent the 30 articles of the Declaration) but not as good ...
As for the Wikipedia list, well, there are a few minor mistakes. For example, the date of issue of the Italian "Human Rights" coin was 10 December (which was actually the 60th anniversary of the declaration). Now how many pieces were minted, I still trust the government bulletin more

which talks about "un contingente in valore nominale di Euro 5.000.000, pari a 2.500.000 pezzi". That is, a total face value of €5,000,000 equalling 2,500,000 pieces.
And by the way, I don't think that the German €2 "Lower Saxony" coin will show St. Andrew's in Hildesheim. This was just a temporary error in the Bundesbank's list

Right, the list of €2 commems issued so far is quite comprehensive. May not be that bad after all that the number of issues (apart from special common issues) is limited to one per country and year. And if you focus on the European Union member states (leaving Monaco, San Marino and the Vatican out), such a collection is still affordable ...
