Another display of how centralised currency minting can go horribly wrong. I believe Hungary had the worst hyperinflation ever at 41,900,000,000,000,000% for July 1946, meaning prices doubled every 15 hours.

You'd have to take a day's wage back home in a wheelbarrow, and by the time you woke up the next day, it was almost worthless.

Hyperinflation happened in Germany and led some people to do some very drastic things. Germany learnt from their mistakes though and have one of the most stable currencies in the world.
