The Reverse – Royal Elegance
The value side features the masterfully designed portrait of King Charles III by Jody Clark. The royal effigy is framed by the technical details: the face value of 5 Niue dollars, the year of issue 2025, and the weight specification "2 OZ 999 SILVER". This classic design forms a harmonious contrast to the colorful design side.
