20 Dollars Watergate

Liberia's early 2000s commemorative program was frankly a collector-market operation dressed as sovereign coinage — the country issued dozens of themed silver pieces during this period, most with negligible domestic circulation and a primary market in European and American novelty collectors. The Watergate issue belongs squarely to that category.

The break-in occurred June 17, 1972; Nixon resigned August 9, 1974 — the first U.S. president to do so.
