Philippine 1,000 Pesos Banknote, 2022, P-W24(1-1), Polymer, UNC - Prefix AA

The 2022 Philippine 1,000 Pesos banknote represents a major milestone in the nation's numismatic history as the first denomination printed on a polymer substrate. This issue transitions from traditional historical portraits to a theme focused on biodiversity, featuring the critically endangered Philippine Eagle and the national flower, the Sampaguita, on its obverse. This shift reflects a modern focus on environmental conservation and national identity through the country's unique natural symbols. The reverse of the note celebrates the Philippines' marine and cultural heritage, depicting the Tubbataha Reefs Natural Park, a South Sea pearl, and intricate T’nalak weave patterns. Security is significantly enhanced through advanced features such as a large vertical transparent window containing iridescent details, a rolling-bar effect on the value panel, and tactile marks for accessibility. As an uncirculated example from the initial AA prefix series, this note is a significant specimen for collectors documenting the evolution of modern currency technology and the rich ecological tapestry of the Philippines.
