5 Dollars - Charles III Viljandi

Niue has operated as a prolific bullion and collector coin issuer since the 1990s, leveraging a currency agreement with New Zealand that permits the island — population under 2,000 — to issue legal tender denominated in New Zealand dollars and, separately, in its own face-value series. The Viljandi issue sits within a broader series of Charles III coins tied to Estonian municipal themes, a pairing that has no geographic or historical logic beyond the licensing arrangements that drive modern commemorative programs.

At 2g of .999 gold, the piece functions as a fractional bullion token more than a coin in any traditional sense.
