10 000 000 Dinara

By mid-1993, Yugoslav inflation had become one of the worst hyperinflationary episodes ever recorded, ultimately reaching a monthly rate exceeding 300 million percent by December. This 10,000,000-dinar note was obsolete almost before it could circulate — within months, denominations in the hundreds of billions were being printed by the same Belgrade facility. The entire series became worthless so rapidly that many notes were never spent at all, which gives surviving examples a misleadingly uncirculated appearance despite the chaos of their moment.

ZIN had been producing Yugoslav currency since the interwar period and printed the full hyperinflationary cascade domestically throughout 1993, an unusual circumstance given that many distressed economies outsource emergency high-denomination printing.
