5 Dollars - Charles III Věra Čáslavská

Věra Čáslavská won four gold medals at the 1968 Mexico City Olympics weeks after signing the "Two Thousand Words" manifesto opposing Soviet occupation of Czechoslovakia. She was the only prominent Czech athlete to publicly refuse to bow her head during Soviet medal ceremonies at those Games. The regime made her pay for it — stripped of her coaching position, barred from international travel, and effectively erased from official sport for over a decade until the 1989 Velvet Revolution restored her standing.
