All banknotes and coins of this common currency are legal tender within all the countries, except that low-denomination coins (one and two cent) are phased out in some of them. The banknotes look the same across countries, while coins have a standard common design on the reverse, expressing the value, and a national country-specific design on the obverse. The obverse is also used for different designs of commemorative coins. The design of the obverse does not affect the coin's acceptability.
