I am the currency of a country that is home to the world's largest active volcano, Mauna Loa, and boasts a unique ecosystem with many endemic species. I am also associated with a state that was once an independent kingdom with a rich Polynesian culture and is now known for its beautiful beaches and surfing.

1. My currency is one of only two currencies in the world that is printed and used in only one country.
2. My name comes from a word meaning 'silver' in Spanish.
3. My coins and banknotes often feature portraits of the monarchy, such as Queen Liliuokalani.
4. My currency is managed by the Central Bank of my state.
