20 Dollars Bombardment of Fort Sumter

Fort Sumter fell to Confederate forces on April 14, 1861, after a 34-hour bombardment that opened the Civil War — with zero combat fatalities on either side. The Union garrison surrendered and was allowed to evacuate, making it one of history's more gentlemanly beginnings to a war that would kill 620,000 men.

Liberia's Civil War commemorative program of the early 2000s produced dozens of these .925 silver issues under KM# 400, largely destined for the collector market rather than any meaningful circulation.
