The currency of Papua New Guinea is kina, divided into 100 toea. The name of kina derives from the kina shell, a traditional currency that was in use until the 1960s in the highlands of Papua New Guinea. In commemoration of the old traditions, all kina bills bear traditional currencies of their reverses. The 10 kina note features a tami bowl, a bird of paradise skin, two circular boar tusks strung together, and a wheel from tabu shell money.
