Do European countries still ise francs, deutchmarks and zlotys and such at all, or only Euros?
I'll try to break it down:
Europe is a part of the world.
Most countries in Europe are part of the Europe Union, eg France, UK and Germany. In total 28 countries.
Some are not, eg Russia, Norway and Schweiz.
Some countries are negotiating for membership right now, eg Turkey and Ukraine.
In the European Union 15 countries are part of a monetary union - the European Monetary Union, EMU.
These countries only use the euro - and not their old currency.
Hope this was a fairly good breakdown.
