5 Dollars - Charles III Rio de Janeiro

Niue has operated as a de facto licensing authority for international commemorative coin programs since the 1990s, issuing under New Zealand's currency framework while retaining its own coin-issuing rights. The Rio de Janeiro designation here almost certainly references the Brazilian mint — the Casa da Moeda do Brasil, one of the oldest operating mints in the Americas, founded in 1694 — contracted as the striking facility, a detail that rarely appears on the coin itself but materially affects die quality and surface characteristics specific to that press run.
