1.000.000 Rials

Bank Melli Iran began issuing million-rial denominations in the late 1990s as the cumulative effect of post-revolutionary inflation rendered smaller notes nearly useless for large transactions. By 2000, the rial had lost the overwhelming majority of its pre-1979 purchasing power, and a one-million denomination — unthinkable under the Shah — had become a practical necessity rather than a symbolic statement.

The Pick number remains unassigned in standard catalogs, which suggests this note either circulated in limited quantities, was a specimen or commemorative issue, or has not yet been formally catalogued in the main series. Worth verifying against Iranian central bank records before attributing a definitive issue status.
