5 Dollars - Leonard I Duke of Nain

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 following a dispute with the state government over wheat production quotas. Australian authorities never recognized the claim, though Casley — styling himself Prince Leonard I — operated the territory as a tourist attraction for decades. The principality formally dissolved in 2020 when Leonard's son Graeme, facing financial pressures including unpaid land taxes, announced its closure and reabsorption into Australia.
