Niue's arrangement with the New Zealand Treasury allows it to issue legal tender coins almost entirely as a bullion and collector vehicle — the island's population of roughly 1,600 has no practical use for a 0.5g gold piece. Chichén Itzá was designated a UNESCO World Heritage Site in 1988 and named one of the New Seven Wonders of the World in 2007, which has made it a recurring subject for this kind of fractional gold issue targeting the novelty collector market.
