Zimbabwian dollar has been devalued by 12 zeroes and new banknotes issued today
with a face value of Z$1, Z$5, Z$10, Z$20, Z$50, Z$100 and Z$500

You have until 30 June to redeem yours.

Competition time. What will your note be worth by 30 June?
Clue - when you made this post your note was worth approx $10
2 minutes ago I checked and it is now worth $2.67

Not as bad, but did you have any of the Argentinian notes from around 1990?
