10 Dollars - Leonard I Sovereign of Hutt

The Principality of Hutt River was declared in 1970 by Leonard Casley, a wheat farmer in Western Australia who seceded from the state in a dispute over crop quotas. The legal arguments Casley used — drawn creatively from obscure Crown prerogative statutes — were never formally accepted by Australian authorities, though the Commonwealth apparently decided prosecution was more trouble than it was worth. The micronation operated for over fifty years, issuing passports, stamps, and coinage throughout.

These pieces were sold primarily as novelty souvenirs to the roughly 40,000 annual visitors the province attracted at its peak.
