Via the settings of the tool, you can make a selection of which coins/bills and which currency you want to practice with.
Currency
The tool is set to use the US Dollar as standard, but you can also choose to use the Canadian Dollar, Mexican Peso, Euro, or British Pound.
Maximum Generated Value
Here you select the highest money total that will be shown if you select "Generate" in the tool.
Arrangement
If you select the box "Order generated money by value," all of the money will be sorted by size in the square when you select "Generate."
Choose Money Values
In this option, you can select which coins or bills to show in the tool. Use this if you, for example, only want to work with coins.
