1 Dollar Maroon Clownfish, colored

Palau's authority to issue legal tender coinage is delegated by agreement with the United States, whose dollar it uses domestically — an arrangement that has made the island nation one of the more prolific producers of novelty collector issues since the 1990s. The colored marine series exploits Palau's genuine status as a globally recognized dive destination, though the coins themselves have no practical circulation history.

KM#406 is copper with silver plating, a construction method that makes long-term surface stability a legitimate concern for storage.
