5 Dollars - Elizabeth II Ammonite

Niue functions as a self-governing territory in free association with New Zealand, and its coin program is operated almost entirely as a licensing arrangement with foreign mints and bullion dealers — the island's actual GDP is small enough that numismatic revenue constitutes a meaningful portion of government income. This ammonite issue is one of hundreds of thematic collector pieces Niue has lent its name to, with little connection to the territory itself beyond the legal authority to strike currency.
