Philippines 1 Piso Banknote (1969-1973 Pilipino Series)

This is a 1 Piso banknote from the 'Pilipino Series' issued by the Bangko Sentral ng Pilipinas between 1969 and 1973. The banknote is vertical in orientation and features the portrait of Philippine national hero José Rizal on the obverse. The note is rectangular, approximately 160mm x 66mm, printed on a cream-colored cotton-linen security paper. The primary ink color is a blueish-grey. Notable markings include the serial number 'GB038429' printed in black in two locations. The seal of the Bangko Sentral ng Pilipinas is prominently displayed in the center. Inscriptions are in Tagalog, reading 'REPUBLIKA NG PILIPINAS'. The condition indicates significant circulation; visible horizontal fold lines cross the center, and there is a noticeable vertical crease. The edges show signs of mild handling and wear, including rounded corners and minor fraying of the paper fibers. The engraving quality is high, featuring intricate guilloché patterns and security micro-printing. This specific series replaced the English series, marking a historical shift toward nationalistic language in Philippine currency. The note is currently stored in a protective clear plastic sleeve, which has preserved it from further environmental staining, though a slight natural patina or toning of the paper is evident due to age.
