Yes. The Euro banknotes are a single design across all the member countries of the Euro zone. There have been two different issues of banknotes now with the redesign in 2012. You cannot tell which individual country they came from. The coins have one common and the other side has a design decided by the specific country that issued them. In both cases (notes & coins), the money can be used anywhere within the Euro countries. Not all countries in Europe accept them. You can see the Euro zone countries on the European central bank website here: https://www.ecb.europa.eu/euro/intro/htm... There are also images of the banknotes and coins.
There are not actually French Euros and German euros - there are just Euros. Like there are not Alabama Dollars and New York dollars - just US Dollars. Some Euro coins have a country on them, but they are like the US quarters with a state on them. It is just decoration and the coins are still Euros.
The Euro is the common currency for much of Europe but not all of the countries use the Euro. A few, such as the UK, retained their pre-European Union currency.
Each country in the Eurozone has its own design on Euro notes, and has the right to mint its own coins with country specific images. However, this money is used all over the Eurozone. For example, in France you will see notes and coins from Spain, Germany, Austria etc - different designs but exactly the same money.
Of course: Euro is short for Europe....There are exceptions. Switzerland has its own currency and so does England (though England of course is not part of the continent...)
pretty much, it's just that some stores will refuse the big ones (100, 200, 500 euro)
Yes, you can. But not in all of Europe, just in most EU countries.
The UK and Denmark kept their own currencies even though they are EU member states, and Switzerland is not in fact an EU country.
Yes, You can.You can use them in all Europe, You'll have to change only for England.
Yes you can :-)
