2 Dollars - Elizabeth II St. Vitus Cathedral

St. Vitus Cathedral in Prague took nearly 600 years to complete — construction began under Charles IV in 1344 and wasn't finished until 1929. Niue has operated as a prolific licensing hub for commemorative silver programs since the 1990s, issuing coins under agreements that funnel royalty revenue to its roughly 1,500 residents while the actual minting occurs elsewhere, typically in European facilities.
