2 Dollars - Charles III Bone Shaker

The "bone shaker" — properly the velocipede — was the direct predecessor to the modern bicycle, its iron-banded wooden wheels transmitting every cobblestone directly through the rider's spine. Commercially viable versions proliferated across Europe and North America roughly between 1865 and 1870, before the penny-farthing displaced them. The Solomon Islands has issued novelty bullion under its sovereign charter since the early 2000s, licensing designs entirely unrelated to its own history or economy — a practice common among smaller Pacific island nations whose mint revenue depends on collector demand rather than circulation.
