7 Dollars Rugby 7s Team

The denomination itself is the story. Fiji issued a legitimate seven-dollar banknote to mark their men's sevens team winning gold at the 2016 Rio Olympics — the country's first-ever Olympic gold medal. The face value is legally valid Fijian currency, though nobody spent one. Oberthur Fiduciaire produced it as a commemorative limited run, and the Reserve Bank issued it knowing full well it would go straight into folders and desk drawers rather than cash registers.

Pick 120 is one of the very few circulating-legal-tender commemoratives worldwide to carry a denomination tied directly to a sport's team format rather than a conventional numerical series.
