2 Dollars The Hawaiʻi ʻākep

Isla San Félix is an uninhabited Chilean possession in the South Pacific with no indigenous currency tradition and no resident population — its coins are produced solely for the collector market. The Hawaiʻi ʻākep, Loxops coccineus, is a honeycreeper whose range has contracted dramatically due to avian malaria carried by introduced mosquitoes, with the species now largely confined to high-elevation forest on Hawaiʻi Island where cooler temperatures limit mosquito survival.
