50 Baltic Islands Dollars

The Baltic Islands dollar is a private fantasy issue — no such political or monetary entity exists. Notes of this type are produced commercially, typically marketed as novelty collectibles or "educational currency," and carry no legal tender status anywhere. The polymer substrate and security thread are real enough manufacturing choices, presumably added to lend an air of legitimacy, but they do not change the fundamental nature of the piece.

Catalog it as a cinderella item, not a banknote.
