Curacao & Sint Maarten P-1-2-3-4 Set 10 20 50 100 Guldens 2025 UNC—New Currency!

The World's Newest Currency, and Perhaps Its Most Beautiful

The world's newest currency was born on March 31, 2025 when Curacao and Sint Maarten launched the Caribbean Guilder (ISO Code: XCG). Both islands are countries (self-governing, but not independent) within the Kingdom of the Netherlands.

Previously they, together with three other smaller islands, formed the Netherlands Antilles, which was disbanded on October 10, 2010 (10/10/10). Curacao and Sint Maarten became their own "countries" within the Kingdom, and the 2 small islands Saba, St. Eustatius and Bonaire politically became part of the mainland (European) Netherlands, but with one quirk: they started using the US dollar, not the Euro. Side note: Aruba had already left the Netherlands Antilles in 1986 to become its own "country" within the Kingdom, and launched the Aruban Florin (ISO code: AWG, browse our Aruba gallery).

It took Curacao and Sint Maarten 15 years to finally replace the Netherlands Antilles Guilder (ISO code ANG) with a new joint currency, the Caribbean Guilder. The Guilder is better known to collectors worldwide by its Dutch name Gulden. Both the old ANG and the new Caribbean Guilder or XCG are fixed to the US Dollar at 1.79 Guilders to 1 Dollar.

The banknotes feature marine life on the front and some of the most beautiful sights of the islands on the back.

See the  page on Caribbean Guilder banknotes at the website of the islands' central bank.
