This banknote is a genuine 500 Billion Dinar banknote from the republic of Yugoslavia. It was issued on December 23, 1993, at the height of a runaway inflation rate that exceeded 313 million percent per month at its peak. This rare and unique note has the most zeros of any banknote ever issued anywhere in the world. This is an absolute must for all paper money collectors and its acquisition will make you an instant billionaire :~).
