5 Dollars - Leonard I Grand Duke of Hutt

The Principality of Hutt River was a self-declared micronation established in 1970 by Leonard Casley, a Western Australian wheat farmer who seceded from Australia in a dispute over wheat production quotas. It was never recognized by any sovereign government. These coins circulated as novelty legal tender within the claimed territory — roughly 75 square kilometers of farmland north of Geraldton — and were sold primarily to tourists and collectors. Hutt River formally dissolved in 2020 when Casley, then in his late nineties, relinquished the claim and the land was reabsorbed into Western Australia.
