1 Dollar - Charles III Slovakia

Niue has operated as a platform for licensed numismatic programs since the 1990s, with the New Zealand government backstopping its legal tender framework. The amber insert here is Baltic in origin — fossilized tree resin, typically 40–50 million years old — sourced through specialist suppliers who cut and polish small calibrated cabochons for coin insertion. The Slovakian connection likely ties to the growing central European market for collector issues featuring regional natural history themes.
