The Pitcairn Islands is a non-sovereign British overseas territory in the Pacific Ocean. Having a population of fewer than fifty people, the territory has no need for local coinage and uses the New Zealand dollar as a medium of exchange. Pitcairn Islands began issuing its first commemorative coins in 1988. Though the Pitcairn Islands dollar is not a true currency in the strict sense of the word and is not used as circulation coinage, it can be lawfully exchanged as tender and is considered a variety of the New Zealand dollar (although it is not legal tender in New Zealand). The Pitcairn Islands dollar exists only because of the coin collecting market, which provides a major staple for the tiny island nation.
The coins are struck by various foreign mints and use internationally popular formats, such as the one half of a troy ounce (1/2oz) of gold size. |
