It’s true. Here’s another angle that I know of:
After WWII, Hungary was printing 1 million mark notes so fast that they only had time to print them on one side and it took a whole sack full of these notes to buy a loaf of bread.
At one point, Zimbabwe took 6 zeros off of their money. (Like that would help.)
Japan only deals in yen. If you got paid $100, it would be like 10,000 pennies.
