2 Dollars Spiny Leaf Insect

Palau's legal tender collector coinage is produced entirely under licensing arrangements — the islands have no domestic mint — and this series was struck specifically for the European novelty market rather than any form of local circulation. The Spiny Leaf Insect (Extatosoma tiaratum) is native to Australia, not Palau, which tells you everything about the geographic logic underpinning the series.
