100 Dollars - Leonard I Nuclear Fusion

Hutt River Province, the self-declared independent principality carved out of Western Australian farmland by Leonard Casley in 1970, issued a series of speculative palladium coins in 1989 timed precisely to the cold fusion frenzy triggered by the Pons and Fleischmann announcement in March of that year. The scientific community's brief, credulous excitement about room-temperature nuclear fusion made palladium — a key element in the disputed experiments — suddenly newsworthy, and several private and semi-official minters moved fast to capitalize.

X#25 placement confirms this as a Unusual World Coins-catalogued non-standard issue. Hutt River's numismatic program was a genuine revenue stream for the principality, and these palladium pieces were sold at substantial premiums over spot into collector markets in Australia, Europe, and North America.
