50 Florin

Aruba separated from the Netherlands Antilles on 1 January 1986 under a special "Status Aparte" arrangement, gaining its own central bank and, critically, its own currency. The florin has been pegged to the US dollar at a fixed rate of 1.79 AWG since that year — a peg that has held without realignment for nearly four decades, which is why the Centrale Bank has been able to issue notes in an orderly series without the emergency reprints and overprints that tend to complicate Caribbean monetary history.

Crane Currency, based in Dalton, Massachusetts, has supplied security paper and printed banknotes for the US Federal Reserve for well over a century, making them an unusual but entirely credible choice for a small island issuer prioritizing authentication technology over cost.
