These countries together have a population of 327 million.
One euro is divided into 100 cents. While each official euro member as well as Monaco, San Marino and Vatican issues its own coins with a unique obverse, the reverse as well as all bills look the same throughout the eurozone. Nonetheless, every coin is legal tender in any of the eurozone countries.
Major currencies other than the Euro are not acceptable as an over the counter currency. In the past, they were widely accepted years ago and changed on the fly at restaurants and bars. So if you have dollars or pounds, it's best to change them at the plethora of exchange bureaus or banks across the island prior to going out.
