20 Euros Pattern

Martinique has no monetary authority of its own — it is a French overseas department, and the euro is its official currency by extension of French law. This piece is a pattern in the strictest sense: never authorized, never circulated, issued outside any legitimate mint mandate. These euro-denominated fantasy pieces attributed to French overseas territories appeared in the early 2000s from private minting operations exploiting the novelty of euro adoption. X# prefix in the Krause system confirms non-standard status.
