500.000 Rials

Bank Tose'e Saderat Iran — the Export Development Bank of Iran — is a specialized state-owned bank, not the central bank, which makes this a somewhat unusual note: a high-denomination instrument issued outside the standard Markazi Bank framework. By 2000, Iran's cumulative inflation since the 1979 revolution had rendered 500,000 rials a functional rather than exceptional sum, but the denomination still signals this was likely intended for institutional or interbank transactions rather than retail circulation.

The Pick number remains unassigned in standard catalogs, suggesting limited documentation in Western reference literature — not uncommon for specialized Iranian banking paper of this period.
