5 Dollars - Leonard I F-15E Strike Eagle

Hutt River Province declared independence from Australia in 1970 after a wheat quota dispute threatened to bankrupt Leonard Casley's farm. Casley — who styled himself Prince Leonard I — exploited an obscure provision of Western Australian law to secede, and the micronation survived largely on stamp and coin sales to collectors rather than any genuine economy. This F-15E issue belongs to that collector-revenue tradition: the Strike Eagle had no connection to Hutt River, which maintained no military and had no foreign policy entanglements with the United States.

Hutt River eventually dissolved in 2020 when Leonard's son Graeme announced closure, citing tax debts to the Australian government.
