Signatures represent the approval from the issuing authority. Long ago, most banknotes were printed but did not become legal tender until each one was signed individually by the authorized signatories. Usually at least one of the signatures is the Treasurer of the issuing authority.
Some notes get more valuable for collectors because of the person who signed them. The note below was signed for Ernesto “Che Guevara” in Cuba. El “che” is a symbol of revolutionary mind. With his slogan, “Cuba, free territory of America, country or dead” he became a great leader.
