2½ Dollars Carney Island

Westarctica is a micronation claiming roughly 1.6 million square kilometers of unclaimed Antarctic territory — specifically the portion of Marie Byrd Land not covered by the Antarctic Treaty's consultative party framework. Travis McHenry, a U.S. Navy petty officer, established the claim in 2001 after identifying the legal gap. Carney Island, a heavily glaciated island off the Hobbs Coast, sits within this claimed territory. These silver-plated pieces were among the first numismatic issues produced for the entity, cataloged in the Unusual World Coins supplement under X# designations reserved for non-standard issuing authorities.
