1 Dollar - Charles III Tyrannosaurus Rex

Niue has operated as a prolific bullion and collector coin issuing authority since the 1990s, leveraging a longstanding currency arrangement with New Zealand to produce legal tender issues under its own name. The paleontological theme here is commercially driven — the dinosaur series has sold well in Asian and American collector markets where small-format gold appeals to entry-level buyers. At one gram, this is essentially a novelty bullion piece rather than a circulation issue; Niue's actual population hovers around 1,500.
