I got this banknote off of ebay .as you can see it is from Yugoslavia (Jugoslavia).
Jane: How much is this banknote worth?
Eli: 50 Billion dinara, which is about 1/10th of a cent.
Jane: Oh my gosh! Why is worth so little? It's so beautiful!
Eli: They had mega-hyperinflation.
Jane: When is this from?
Jane: It's not Yugoslavia anymore, is it?
Eli: Now it is: Serbia, Montenegro, Kosovo. It used to be bigger than that before 1990.
