I know someone who collects bills or notes and coins from different countries. Every time someone she knows or a relative comes home from abroad, she would ask for a bill or two or some pennies to add up to her collections.

When she travels too, she would make sure that she saves one paper bill. She also got  some morgan silver dollars, some Middle Eastern currency bills, a couple of European notes and Asian bills. She has got a really cool collection and I know she loves all her pieces to bits. I hope she can get more bills from other countries too, I am certain she would be so delighted to complete her collection.
