500 Rials 1971 'light panel' issue

The "light panel" designation separates this issue from the earlier P#92 printing, where the security panel threading through the paper appears markedly darker — a subtle but reliable diagnostic for collectors working through the Harrison-printed Iranian series of this period. Amouzegar served as Minister of Finance under the Shah across multiple administrations, which accounts for his signature appearing alongside three successive Bank Markazi governors; his continuity in that role was unusual even by Iranian standards.

The 1971 dating anchors this note to the height of oil-revenue expansion under Mohammad Reza Shah, when 500 Rials still represented meaningful purchasing power before inflation eroded the denomination's practical standing through the mid-1970s.
