The My Money Around the World app shows you literally all the currency around the world. From the US Dollar to the European Euro. Those you know, but what about the Bermudian Dollar or the Djiboutian Franc?
My Money Around the World can show you the answer to that. It contains all the banknotes and coins of every land/country around the world.
With the search option you can search for the currency or scroll through the database until you find an interesting one.
The search option can also be used as a general search, like you plan to go on vacation to somewhere like Malaysia. MyMoney will show you some info about Malaysia and also what currency is used there. From here go to the Malaysian Ringgit and discover the banknotes and the coins.
