100 Dollars - Leonard I

The Principality of Hutt River was proclaimed by Leonard Casley in 1970 after a dispute with the Western Australian government over wheat production quotas that threatened to bankrupt his farm. Casley exploited an obscure provision of imperial law — never successfully tested in court — to claim secession, and the Australian government's failure to formally challenge it in time left the declaration in a legal grey zone it never fully escaped.

This 1976 gold issue came early in Hutt River's numismatic program, which became the micronation's primary revenue stream within a few years of its founding.
