List of world's currencies with values?

If you're talking about coins, you are surely aware that question would take several megabytes of space to answer. Go to your library and look for a book called The Official Black Book Guide to World Coins. It's about the size of a very large dictionary and will give you enough information to answer most typical questions about world coins.

If you're referring to exchange rates, your best bet is to use a site such as www.xe.com or CNNMoney, because exchange rates change daily. Any numbers posted here, even for the major currencies such as the euro, pound, Australian and U.S. dollars, would be out of date within a day or so.
