25 Dollars - Leonard I U.S. MIM-23 'Hawk' Surface-to-air guided missile

Hutt River Province — the self-declared micronation established by Leonard Casley in Western Australia in 1970 after a dispute with the state government over wheat production quotas — issued a remarkable volume of numismatic curiosities through the late 1980s and early 1990s, most aimed squarely at the thematic collector market. This piece, commemorating the MIM-23 Hawk missile system, belongs to a series of military hardware coins that had no plausible connection to Hutt River's sovereignty or history.

The Hawk missile entered U.S. service in 1960 and saw combat use by multiple allied nations, most notably by Israeli forces during the 1973 Yom Kippur War.
