Zimbabwe changed to a different method to count money, they changed to the centimeter. Street vendors would have a table with piles of bundled notes lying next to it in the open, otherwise known as small change. Sent a few trillion dollar bills to the States and other places, it was actually hard to get this currency, as the Zimbabweans could not figure out that people though the notes were actually worth anything, they regarded them as poor quality toilet paper.
The present currency is either the US dollar ( plenty of fakes there of course) or the South African Rand. Still have some multi thousand Zimdollar bills.
