Philippine banknotes include issues of the Philippine peso, reflecting the country’s economic, political and cultural development from the early 20th century to the present. The series feature historical figures, Filipino cultural heritage, architectural landmarks, natural landscapes, local fauna and symbolic motifs representing national identity, accompanying monetary reforms, modernization phases and periods of economic development. Due to their design variety, variants, signatures and historical relevance within Southeast Asia, Philippine paper money is appreciated in international numismatics and sought after by world banknote collectors.
