Zimbabwe issues a $10 million currency bill

The Central Bank of Zimbabwe issued a $10 million currency bill, the highest denomination of currency in the world. Although it seems like a lot on paper, it's actually less than $4 US. The current inflation rate in Zimbabwe is 50,000 per cent a year.
Zimbabwe’s problems continue to mount with a hyper inflation in their economy. To combat this, Zimbabwe’s central bank has issued a $10 million Zimbabwe bill, which is worth only $4 US.
