20 Dollars Athens Olympic Games - Water polo

Liberia's Olympic commemorative program in the early 2000s was prolific to the point of controversy — the Central Bank issued dozens of silver pieces tied to the 2004 Athens Games, most destined for the collector market rather than any domestic circulation. Water polo returned to its modern home at Athens, where the sport had first appeared in the 1896 program, making the thematic choice at least historically grounded.

KM# 520 is one of the longer series in this run. Collector demand was modest at issue and has remained so.
