100 Rials 1969 'dark panel' issue

The 'dark panel' designation distinguishes this issue from an earlier, lighter-toned version of the same Harrison-printed series — a chromatic shift in the security panel background significant enough to warrant separate catalog treatment. Harrison had held the Iranian contract for years by this point, and the High Wycombe facility was producing some of the most technically sophisticated intaglio work in the world during this period.

Two signature combinations are recorded. Amouzegar served as Minister of Finance under the Shah and later became Prime Minister in 1977; Farmanfarmaian was Governor of Bank Markazi before him. The transition between signatories places this issue squarely across a period of accelerating oil revenue and monetary expansion.
