The European Commission has said that it is extremely satisfied with the euro's first full working day, which passed off largely without incident.
Central banks throughout Europe reported a smooth initial transition from their old currencies to the euro. The financial markets have also responded positively to the euro.
So far, the transition to the euro has run very smoothly. The Euro Changeover Board of Ireland says that over 85% of ATM machines are working normally and dispensing euro.
The Central Bank says that there have been no problems, and that the changeover is going well. The Central Bank and all other banks and building societies around the country are changing punts to euro free of charge.
The Office of the Director of Consumer Affairs has received a steady stream of calls from the public looking for information, but they say that they too have no major problems to report.
However, Austrians have not been so lucky. All of Austria's 2,500 cash machines broke down a day after they were converted to dispense new euro cash. The machines stopped working at lunchtime when a central computer crashed.
The problem was fixed after about an hour. A spokesman for the company that runs the ATM machines denied the breakdown was due to overuse by customers trying to get the new euro notes.
The euro has marked its first day in commercial use by rising against foreign currencies. Earlier today it was worth 90.2 US cents, and 62.25p sterling.
Economists say that while the euro's debut as actual currency has given it a boost, its long term value will have more to do with confidence in the performance of the 12 euro-zone economies.
