post WW2 Hunagry had a 1,000,000,000,000,000,000,000 pengo note because inflation was soo bad, at the end of it all, the entirerety of all the Hungarian notes was worth less than a single cent by the time they switched to a different currency. Post WW1 Germany also had similar problems because they thought they could pay off their debts by printing more money. It got soo bad that you had to carry a wheelbarrow full of cash to buy a loaf of bread. Robbers would just take the wheelbarrows because they were worth more than the cash they contained. So yeh, that's hyperinflation for you.
