They used to have their own local versions of the franc in Monaco or lires in San Marino and the Vatican before the introduction of the euro. These currencies were connected to the French franc and Italian lire. When France and Italy changed their currency for the euro, they just joined as well.
I was happy to see there are country names on many of these coins (Andorra, Latvia, Lithuania, Slovenia, Monaco, Estonia, Cyprus...), but I guess that defies the idea of this quiz...
And I'm sure they've got some tourist shops in their museums.
