A Nguza nguza (aka nusu nusu aka musu musu aka toto isu) is a traditional figurehead that Solomon Islanders used to affix to the fronts of their canoes, at the waterline, to provide supernatural protection.
While the coin only shows the head, they were traditionally full-bust figures with large heads and circular ear ornaments. The hands are clasped under the chin, usually holding another head (as in this depiction) or a bird.
The original 7-sided Nguza nguza dollar was replaced in 2012 with this smaller, round version.
