To answer your question: In Germany, I also encountered euro coins with the markings of Spain and the Netherlands. It would have been great to have held euros from the Dutch, the Spanish, the Italians, and the French all in one hand, showing how far we've come since World War II.
I understand the sentiment there - but the people's of those countries are getting more and more irritated by their "new" currency. With a real almost 50/50 like/dislike its actually becoming quite devisive.
I won't go on as its not much relevant to metric/imperial
