10 Rials World Jerusalem Day, small type

World Jerusalem Day — Ruz-e Jahani-ye Qods — was proclaimed by Ayatollah Khomeini in 1979, designating the last Friday of Ramadan as an annual occasion of political solidarity. Iran issued commemorative coinage tied to this observance through the 1980s, though the "small type" designation on KM#1253 reflects a mid-series die modification rather than a planned variant — the reduced design elements distinguish it from the earlier, larger-type strikes of the same nominal issue.
