20 Dollars Athens Olympic Games - Volleyball

Liberia's Olympic commemorative series of 2004 was one of dozens of collector-market issues produced by various small nations with no direct connection to the Athens Games — licensed through third-party minting arrangements, typically with European mints, and sold exclusively to the numismatic trade rather than circulating domestically. Liberia itself was in the final stages of a brutal civil war when these were struck, its own currency system effectively non-functional.
