20 Dollars - The Byers' Island

Byers Island — also called Bajo Nuevo Bank — is a submerged reef platform in the western Caribbean claimed at various times by the United States, Colombia, Nicaragua, Honduras, and Jamaica. The U.S. claim rests on the Guano Islands Act of 1856, which authorized American citizens to claim uninhabited islands for guano extraction and extended U.S. jurisdiction over them. Bajo Nuevo was claimed under that statute but has never been formally incorporated, administered, or permanently occupied by any American authority.

No territorial government has ever issued currency for Bajo Nuevo. This note has no official standing.
