5 Dollars - Charles III Oru Palace

Niue has operated as a bullion and commemorative coin program essentially since 1987, licensing its currency authority to generate revenue its tiny population — around 1,500 people — could never produce through domestic circulation. The island uses the New Zealand dollar in daily commerce; these legal tender issues exist purely as collector vehicles produced under contract, typically by the New Zealand Mint or the Perth Mint.

The Oru Palace in Tallinn served as a Soviet-era government residence before Estonian independence in 1991 restored it to civilian administration.
