Slovakia has officially replaced its old currency (the koruna) with the Euro, and is now the 16th official member of the Eurozone. The Eurozone is not the same as the European Union, as to be a member you must use the Euro as your official currency.
Currency Exchange in Europe
If nothing else, the Euro is the smartest currency I have ever used. I don’t mean from any kind of economical standpoint, but rather from a design perspective. The Euro has a very user friendly design template. Paper Euros have color and size discrepancies. Coins, which come in denominations of €2, 1, .50, .20, .10, .5 .02 and .01 all have different weights and ridges on the side. This means that the blind can use all kinds of currency with much more ease.
The €2 Euro coins are similar to what the United States did with quarters over the past 10 years, except the coins are only released in their respective countries. Each country may produce commemorative coins every year. Typically they commemorate historically relevant anniversaries or draw attention to important special events. As of 2008, fifty variations of €2 commemorative coins have been minted. The €2 coins not only make great collecting, they can teach you about history!
It’s important to keep track of the coins you have as you may end up with something worth more than €2. This is why I always keep either a fanny pack or a coin purse with me when I travel. I prefer the coin purse, as the fanny pack isn’t quite the hippest invention. Coins worth €5 and €10 are sometimes used in general transaction. Higher amounts than €10 are extremely uncommon; however some countries have minted coins worth as much as €200, so it may be worth it to double check all your coins. It would be a shame to use a €100 coin to pay a €1 toll while in your rental car in Europe!
