Niue has operated as a reliable vehicle for themed bullion and collector coinage since the 1990s, its arrangement with New Zealand granting it the legal framework to issue currency while its tiny population — under 2,000 — ensures none of it sees domestic circulation. The "Metropolis" designation here refers to the 1927 Fritz Lang film, a recurring subject in numismatic licensing programs targeting cinema collectors.
