Twenty years ago, on 1-Jan-1986, Portugal and Spain joined the European Communities. The two countries commemorate the anniversary with coins that show a map and a bridge. Maybe not the most thrilling design idea ever

but what I find neat is that basically the same design is used for both issues.

(The other side of the Spanish piece shows King Juan Carlos as usual.)
