5 Dollars - Leonard I Koala

Hutt River Province — the self-declared micronation established by Leonard Casley in 1970 after a dispute with the Western Australian government over wheat production quotas — issued a series of silver pieces throughout the late 1980s and 1990s aimed squarely at the collector market. These were never circulating currency in any functional sense, but Casley maintained the legal fiction of monetary sovereignty with considerable persistence, and international bullion dealers played along willingly enough.

The X# prefix in the Krause catalog places this outside conventional national coinage — their classification for fantasy issues and non-circulating locals.
