Zimbabwe currency.
One of my friends Claire emigrated from Zimbabwe to Australia a few months ahead of us.
She has watched the currency go into freefall and gets emails from friends left behind in Zim telling her how much simple things now cost in the supermarket (if they can even be bought)
Claire sent me on an email from her friend saying that a loaf of bread had cost her $190 000 000 yesterday. The prices change on a daily basis and they are lucky sometimes to be able to afford the basics that we take for granted in our kitchens.
Here is a Five hundred MILLION dollar note that was issued by the Reserve bank of Zimbabwe this month and will only be honoured until the end of this year.
