100 Dollars - State of Florida

Florida is one of several U.S. states that has issued its own currency at various points in its history, but this note is almost certainly a modern novelty or commemorative item rather than a federally authorized instrument. The federal government holds exclusive authority over legal tender in the United States under the Coinage Act of 1965, and no U.S. state has issued circulating paper currency since the National Banking Acts of the 1860s effectively ended that practice.

The hologram security feature on a piece with no federal backing is a curious detail — present to suggest legitimacy it legally cannot have.
