3 Dollars - Charles III Charles IV

Niue has become one of the more prolific issuers of novelty legal tender since the 1990s, operating effectively as a licensing vehicle for foreign mints — this piece, with its embedded wood centre cast within a fine silver ring, falls squarely into that category. The bimetallic wood-in-metal format has been used by a handful of mints since the mid-2000s, with the Austrian Mint among the earliest to commercialize it at scale.

The Charles III / Charles IV pairing almost certainly references the Spanish monarchs rather than British ones, given Niue's Pacific issuing history and the commercial appeal of Spanish colonial numismatics.
