3 Tomans Nasr-ed-Din Shah

The Imperial Bank of Persia was itself a British concession — chartered in 1889 under a grant from Nasr-ed-Din Shah that gave it the exclusive right to issue banknotes throughout Persia. That concession, negotiated by Baron Julius de Reuter, was deeply controversial; Iranian merchants and clergy resented the bank's foreign ownership, and paper currency issued under a British charter circulated in an environment of chronic public distrust.

The date range on this type runs to 1923, long after Nasr-ed-Din Shah's assassination in 1896, meaning the same plate continued printing notes bearing a dead ruler's name for nearly three decades.
