As Antarctica is not a country, but a continent without a permanent population or governing body, there is no official currency or coins specific to this region. Therefore, no foreign coins or currency from Antarctica exist.
Antarctica, being an international research zone, does not have its own official currency or coins. Instead, it uses a mix of currencies from the countries that operate research stations there. This includes the U.S. dollar, Australian dollar, British pound, and more. Some collectible Antarctica-themed coins do exist, but as commemorative or novelty items only.
