500 Dollars Gyeongbokgung

Palau has no meaningful historical connection to Gyeongbokgung — the 14th-century Joseon dynasty palace complex in Seoul — making this one of the more transparent examples of a small Pacific nation licensing its minting authority to produce high-premium bullion for the collector market. The arrangement is entirely legal; Palau has issued coins under similar agreements for decades, with the revenue sharing between the issuing dealer and the Palauan government rather than reflecting any numismatic or diplomatic relationship with Korea.
