1.000.000 Rials

Bank Mellat is one of Iran's large state-owned commercial banks, not the central bank — which makes this a commercial bank draft or instrument rather than a standard central bank note. The Rial's severe devaluation over the preceding two decades meant that by 2000, one million units represented a fairly routine transaction value, not an extraordinary sum.

The Pick number is unassigned, which likely places this outside the standard central bank series catalogued by Krause — possibly a certified cheque, bank draft, or large-denomination instrument issued for interbank or wholesale settlement rather than retail circulation.
