20 Dollars - Leonard I U.S. B-52 Stratofortress Jet Bomber

Hutt River Province — the self-declared micronation carved out of a Western Australian wheat farm by Leonard Casley in 1970 after a dispute with the state government over wheat quotas — issued a sprawling series of gold-plated commemoratives throughout the late 1980s and early 1990s, targeting the collector novelty market rather than any circulating economy. This piece, honoring the Boeing B-52, belongs squarely to that era of themed issues produced for foreign buyers with no pretense of domestic circulation.

Hutt River's coinage is catalogued in the Unusual World Coins supplement under the X-number system precisely because no mainstream numismatic authority recognizes the issuing entity as a sovereign state.
