2 Dollars 50 Cents - Charles III St. John's Church, Viljandi

Viljandi's St. John's Church has stood in various states of ruin and restoration since its 14th-century construction, having been gutted during the Livonian War and left roofless for centuries — the open-sky nave became so iconic that preservationists successfully argued against full reconstruction, leaving it deliberately incomplete. Niue has issued gold fractionals under Charles III's effigy through several such Baltic and Nordic architectural subjects, a program that leans heavily on the collector market for revenue, the island's own economy generating negligible demand for gold coinage of any kind.
