20 Dollars Operation Overlord

Liberia built an entire cottage industry around commemorative silver issues in the late 1990s and early 2000s, licensing designs to foreign minting houses and flooding the collector market with pieces that had no domestic circulation whatsoever. This coin is part of that output — struck almost certainly by a European contractor, nominally denominated in Liberian dollars at a time when the country's own currency was in severe distress following years of civil war under Charles Taylor's government.

Operation Overlord itself was authorized at the Tehran Conference in November 1943, where Stalin pressed Roosevelt and Churchill to commit to a firm date for the Western Front landings.
