1 Dollar Save the Ocean

Palau has issued collector-oriented bullion and themed coinage under licensing arrangements since the 1990s, producing dozens of small-denomination gold and silver pieces annually through foreign minting partners — this piece being one of hundreds in that ongoing program. The "Save the Ocean" series, running across multiple years, was designed primarily for the European collector market rather than any domestic monetary function.

At 0.5g of .9999 fine gold, the practical bullion value is marginal; the premium over spot has always been the point.
