10 Rials World Jerusalem Day, large type

World Jerusalem Day — Ruz-e Jahan-e Qods — was proclaimed by Ayatollah Khomeini in August 1979, designating the last Friday of Ramadan as an annual day of solidarity with Palestinians. This coin was issued in 1982, the same year Israel's invasion of Lebanon put the Palestinian question at the center of regional politics and gave the occasion renewed urgency in Tehran.

The "large type" designation distinguishes it from a nearly identical issue with smaller lettering — a minor but catalogued die variation that matters to type collectors assembling complete sets of the Islamic Republic's early commemorative program.
