These 10 guilders dated 1 January 2006 are money from the last years of a united Netherlands Antilles: the union of islands was dissolved on 10 October 2010. The Antillean guilder then remained only on Curaçao and Sint Maarten, while Bonaire, Saba and Sint Eustatius switched to the US dollar in 2011.

The star of the front is the purple-throated carib, a hummingbird (Eulampis jugularis). The bird series was drawn by the Curaçao artist Oscar Ravelo: it appeared in 1986, after Aruba left the Antilles, and each denomination from 5 to 250 guilders received its own local bird, while the back of every note carries the bank’s seal emblem.

In 1998 the bank strengthened the security features and the series appeared in a second edition: the most obvious novelty is gold foil on the front, which comes out black on a photocopy. Held to the light, the note shows a watermark with the bank’s emblem, and small sparkling dots are scattered along the top and bottom of the back.

For a «birds on banknotes» collection it offers the hummingbird as drawn by Oscar Ravelo, and for a Netherlands Antilles collection it is an issue from the time when the country still existed, pairing with the 2011–2016 tens of the same design. UNC condition means the note has never circulated: no folds, no wear, no soiling, even corners — just as it left the press.
