200.000 Rials

Bank Keshavarzi — the Agricultural Bank of Iran — is a state-owned specialist bank focused on rural credit and agricultural financing, not a central bank. It is unusual for such an institution to issue circulating paper currency; this almost certainly functioned as a bearer instrument, a deposit certificate, or an internal transfer document rather than general-circulation banknote. The Pick catalog reference "P#0" confirms it has not been formally catalogued, which itself tells you something about its rarity or ambiguous classification.

200,000 Rials places this squarely in the high-inflation era of post-revolutionary Iran, when denominations climbed steadily through the 1990s. The use of a watermark and serial numbering on what may be a quasi-banking document is worth noting — modest security by commercial printing standards of 2000.
