40 Reais 2014 World Cup

No entity called "Banco de Cabinda" has ever issued legal tender. Cabinda is an Angolan exclave with no independent monetary authority, no central bank, and no history of coin issuance. This piece has no verifiable issuing body, and "40 Reais" corresponds to no denomination in any recognized currency system. It is a privately produced fantasy item, almost certainly manufactured for the souvenir or novelty market around the 2014 FIFA World Cup in Brazil.
