The Central Bank of Trinidad and Tobago has issued a circulating commemorative $50 note to celebrate the bank's 50th anniversary. The notes have been printed by De La Rue on their Safeguard polymer substrate. The face value is US$8, uncirculated notes will be selling for about double that, once a few eBay dealers have them in stock.
The design is a bit too busy, but it is a vibrant and beautiful note nonetheless.
