500 000 Dinara

Yugoslavia's 1993 hyperinflation was among the most severe ever recorded, eventually reaching a monthly rate exceeding 300 million percent at its peak in January 1994. This 500,000 dinar note was already obsolete within weeks of issue — not through wear, but through denomination redundancy, as the National Bank was forced to release successively larger values in rapid succession. ZIN in Belgrade was printing new denominations faster than the economy could absorb them.

The series was eventually swept away by the January 1994 redenomination, which replaced 1,000,000,000 old dinars with 1 "novi dinar" — itself pegged briefly to the Deutschmark in a stabilization attempt engineered by economist Dragoslav Avramović.
