There is massive increase in prices as you hit the trillions.
” ...Zimbabwe used to have a Z$100,000,000,000,000 note - one hundred trillion Zimbabwean dollars.
The note, along with previous hyper-inflated denominations including Z$10,000,000,000,000 (ten trillion) and $1,000,000,000,000 (one trillion), could be exchanged for U.S. dollars until the end of April 2016, but it was worth only about $0.40. It is fetching significant higher prices as a novelty item on websites such as eBay.”
